It seems this is fixed in Emacs 22.3, here is the relevant change:
2008-05-13 Jan Djärv <jan....@swipnet.se>
* xterm.c (handle_one_xevent): Don't pass buttons higher than 3
to Gtk+ menus.

I cannot test it due to lack of a mouse wheel, so you have to wait for
22.3 to be packaged or apply the patch and build the emacs22 package
yourself (could take a few hours on your old PowerPC machine) if you
want to check whether this is correct. See also the thread starting at
http://lists.gnu.org/archive/html/emacs-devel/2008-05/msg00786.html.
Cheers,
Sven
