After a bit of work, I have modified CCMenuItem to allow the use of Atlas Sprites. Hope this is helpful.

CCMenuItem.h

...
@interface CCMenuItemSprite : CCMenuItem <CCRGBAProtocol>
{
	CCSprite *normalImage_, *selectedImage_, *disabledImage_;
}

/** the image used when the item is not selected */
@property (nonatomic,readwrite,retain) CCSprite<CCRGBAProtocol> *normalImage;
/** the image used when the item is selected */
@property (nonatomic,readwrite,retain) CCSprite<CCRGBAProtocol> *selectedImage;
/** the image used when the item is disabled */
@property (nonatomic,readwrite,retain) CCSprite<CCRGBAProtocol> *disabledImage;

/** creates a menu item with a normal and selected image*/
+(id) itemFromNormalSprite:(CCNode<CCRGBAProtocol>*)normalSprite selectedSprite:(CCNode<CCRGBAProtocol>*)selectedSprite;
/** creates a menu item with a normal and selected image with target/selector */
+(id) itemFromNormalSprite:(CCNode<CCRGBAProtocol>*)normalSprite selectedSprite:(CCNode<CCRGBAProtocol>*)selectedSprite target:(id)target selector:(SEL)selector;
/** creates a menu item with a normal,selected  and disabled image with target/selector */
+(id) itemFromNormalSprite:(CCNode<CCRGBAProtocol>*)normalSprite selectedSprite:(CCNode<CCRGBAProtocol>*)selectedSprite disabledSprite:(CCNode<CCRGBAProtocol>*)disabledSprite target:(id)target selector:(SEL)selector;
/** initializes a menu item with a normal, selected  and disabled image with target/selector */
-(id) initFromNormalSprite:(CCNode<CCRGBAProtocol>*)normalSprite selectedSprite:(CCNode<CCRGBAProtocol>*)selectedSprite disabledSprite:(CCNode<CCRGBAProtocol>*)disabledSprite target:(id)target selector:(SEL)selector;

@end
...

CCMenuItem.m

...
#pragma mark CCMenuItemSprite
@implementation CCMenuItemSprite

@synthesize normalImage=normalImage_, selectedImage=selectedImage_, disabledImage=disabledImage_;

+(id) itemFromNormalSprite:(CCNode<CCRGBAProtocol>*)normalSprite selectedSprite:(CCNode<CCRGBAProtocol>*)selectedSprite
{
	return [self itemFromNormalSprite:normalSprite selectedSprite:selectedSprite disabledSprite:nil target:nil selector:nil];
}
+(id) itemFromNormalSprite:(CCNode<CCRGBAProtocol>*)normalSprite selectedSprite:(CCNode<CCRGBAProtocol>*)selectedSprite target:(id)target selector:(SEL)selector
{
	return [self itemFromNormalSprite:normalSprite selectedSprite:selectedSprite disabledSprite:nil target:target selector:selector];
}
+(id) itemFromNormalSprite:(CCNode<CCRGBAProtocol>*)normalSprite selectedSprite:(CCNode<CCRGBAProtocol>*)selectedSprite disabledSprite:(CCNode<CCRGBAProtocol>*)disabledSprite target:(id)target selector:(SEL)selector
{
	return [[[self alloc] initFromNormalSprite:normalSprite selectedSprite:selectedSprite disabledSprite:disabledSprite target:target selector:selector] autorelease];
}
-(id) initFromNormalSprite:(CCNode<CCRGBAProtocol>*)normalSprite selectedSprite:(CCNode<CCRGBAProtocol>*)selectedSprite disabledSprite:(CCNode<CCRGBAProtocol>*)disabledSprite target:(id)target selector:(SEL)selector
{
	if( (self=[super initWithTarget:target selector:selector]) ) {

		self.normalImage = normalSprite;
		self.selectedImage = selectedSprite;
		self.disabledImage = disabledSprite;

		[self setContentSize: [normalImage_ contentSize]];
	}
	return self;
}

-(void) dealloc
{
	[normalImage_ release];
	[selectedImage_ release];
	[disabledImage_ release];

	[super dealloc];
}
-(void)setPosition:(CGPoint)p
{
	if (normalImage_.usesSpriteSheet==TRUE) {
		if(isEnabled_) {
			if( isSelected_ )
				[selectedImage_ setPosition:p];
			else
				[normalImage_ setPosition:p];

		} else {
			if(disabledImage_ != nil)
				[disabledImage_ setPosition:p];

			// disabled image was not provided
			else
				[normalImage_ setPosition:p];
		}
	}
	position_ = p;
	isTransformDirty_ = isInverseDirty_ = YES;

}
-(void) draw
{
	if (normalImage_.usesSpriteSheet==TRUE) {

	}else {

	if(isEnabled_) {
		if( isSelected_ )
			[selectedImage_ draw];
		else
			[normalImage_ draw];

	} else {
		if(disabledImage_ != nil)
			[disabledImage_ draw];

		// disabled image was not provided
		else
			[normalImage_ draw];
	}
	}
}

#pragma mark CCMenuItemImage - CCRGBAProtocol protocol
- (void) setOpacity: (GLubyte)opacity
{
	[normalImage_ setOpacity:opacity];
	[selectedImage_ setOpacity:opacity];
	[disabledImage_ setOpacity:opacity];
}

-(void) setColor:(ccColor3B)color
{
	[normalImage_ setColor:color];
	[selectedImage_ setColor:color];
	[disabledImage_ setColor:color];
}

-(GLubyte) opacity
{
	return [normalImage_ opacity];
}
-(ccColor3B) color
{
	return [normalImage_ color];
}
@end
...

Now with this code you can use sprites rendered using a sprite sheet with CCMenuItemSprite.

This was possible before you wrote any code.

If you added an atlas sprite as a menu item before hand, the game would SIGABRT with the error "Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'If CCSprite is being rendered by CCSpriteSheet, CCSprite#draw SHOULD NOT be called'"

This is a modification to CCMenuItem to allow you to use both Atlas and Non-Atlas Sprites in a CCMenuItemSprite.

I noticed the code I posted above doesn't work with transformations. So I fixed it and made it slightly more efficient.
CCMenuItem.m

...
@implementation CCMenuItemSprite

@synthesize normalImage=normalImage_, selectedImage=selectedImage_, disabledImage=disabledImage_;

+(id) itemFromNormalSprite:(CCNode<CCRGBAProtocol>*)normalSprite selectedSprite:(CCNode<CCRGBAProtocol>*)selectedSprite
{
	return [self itemFromNormalSprite:normalSprite selectedSprite:selectedSprite disabledSprite:nil target:nil selector:nil];
}
+(id) itemFromNormalSprite:(CCNode<CCRGBAProtocol>*)normalSprite selectedSprite:(CCNode<CCRGBAProtocol>*)selectedSprite target:(id)target selector:(SEL)selector
{
	return [self itemFromNormalSprite:normalSprite selectedSprite:selectedSprite disabledSprite:nil target:target selector:selector];
}
+(id) itemFromNormalSprite:(CCNode<CCRGBAProtocol>*)normalSprite selectedSprite:(CCNode<CCRGBAProtocol>*)selectedSprite disabledSprite:(CCNode<CCRGBAProtocol>*)disabledSprite target:(id)target selector:(SEL)selector
{
	return [[[self alloc] initFromNormalSprite:normalSprite selectedSprite:selectedSprite disabledSprite:disabledSprite target:target selector:selector] autorelease];
}
-(id) initFromNormalSprite:(CCSprite<CCRGBAProtocol>*)normalSprite selectedSprite:(CCSprite<CCRGBAProtocol>*)selectedSprite disabledSprite:(CCSprite<CCRGBAProtocol>*)disabledSprite target:(id)target selector:(SEL)selector
{
	if( (self=[super initWithTarget:target selector:selector]) ) {
		self.normalImage = normalSprite;
		self.selectedImage = selectedSprite;
		self.disabledImage = disabledSprite;
		[self setContentSize: [normalImage_ contentSize]];
	}
	return self;
}

-(void) dealloc
{
	[normalImage_ release];
	[selectedImage_ release];
	[disabledImage_ release];

	[super dealloc];
}

-(void) draw
{
	if (normalImage_.usesSpriteSheet==TRUE) {
		if(isEnabled_) {
			if( isSelected_ )
				[selectedImage_ setPosition:[self.parent convertToWorldSpace:self.position]];
			else
				[normalImage_ setPosition:[self.parent convertToWorldSpace:self.position]];

		} else {
			if(disabledImage_ != nil)
				[disabledImage_ setPosition:[self.parent convertToWorldSpace:self.position]];

			// disabled image was not provided
			else
				[normalImage_ setPosition:[self.parent convertToWorldSpace:self.position]];
		}
	}else {

	if(isEnabled_) {
		if( isSelected_ )
			[selectedImage_ draw];
		else
			[normalImage_ draw];

	} else {
		if(disabledImage_ != nil)
			[disabledImage_ draw];

		// disabled image was not provided
		else
			[normalImage_ draw];
	}
	}
}

#pragma mark CCMenuItemImage - CCRGBAProtocol protocol
- (void) setOpacity: (GLubyte)opacity
{
	[normalImage_ setOpacity:opacity];
	[selectedImage_ setOpacity:opacity];
	[disabledImage_ setOpacity:opacity];
}

-(void) setColor:(ccColor3B)color
{
	[normalImage_ setColor:color];
	[selectedImage_ setColor:color];
	[disabledImage_ setColor:color];
}

-(GLubyte) opacity
{
	return [normalImage_ opacity];
}
-(ccColor3B) color
{
	return [normalImage_ color];
}
@end
...

I think the correct way to do it would be to not include it in a SpriteSheet...?

I had the same problem when migrating a game from 0.8 to 0.99.

I had the same problem converting from 0.82 to 0.99.1. Like Joao, I found that not childing the AtlasSprite to the SpriteSheet fixed it.
