Category conflicts with Tiger

I have a large collection of categories that I use for all my apps,
extending the Cocoa classes. (I plan on releasing them publicly when I
get time.)
Reading through the release notes for Tiger, I've noticed several new
methods that conflict with my categories. For example, I have a
NSPopUpButton category that adds the following method, which conflicts
with a new Tiger method:
- (int)selectItemWithTag:(int)aTag;
This one isn't too difficult to resolve (I just need to rename it to
avoid the conflict, with corresponding changes to existing code), but
there are others that are harder to resolve.
One such is a NSImageView category that implements -cut:, -copy:,
-paste:, and -delete:. I see that NSImageView now implements those
natively. I can't simply rename my editions, since then they wouldn't
be used, and can't remove them, as then those functions wouldn't work
when running under Panther. What is the best way to resolve this
conflict? Would calling -setAllowsCutCopyPaste: with NO disable
Cocoa's implementation but let mine continue, or would mine fail too
(since it is a category rather than a subclass). Is implementing them
in a subclass of NSImageView instead of a category the only feasible
solution?
