I can't reproduce it with Emacs 22.1/Mac OS X 10.3.9, and I think I
could have found it if it were the case, because there was another
`column-number-mode'-related problem (not related to Carbon) that I
was debugging just before the release.

Did you really test it with Emacs 22.1?  According to another report,
you seems to be using 22.1.50, not a release version.

It seems that Aquamacs Emacs 1.0 also uses Emacs 22.1.50.  If so (and
1.0 is intended to be an official release version of Aquamacs Emacs),
I'd say it's a ridiculous idea not to use the release version of Emacs
for it.
