What does equery belongs </path/to/32-bit-file> return?  What video
drivers are you running?

If you are running slaveryware video drivers, equery belongs will probably
return them (assuming you merged them using portage, anyway).  If it
returns nothing and you didn't manually (not using portage, so it doesn't
know about the file) install something using that file, it's likely safe to
delete it. Just to be safe, however, I'd rename it to *.2006.07.28.remove
(a month later) or something similar. Then after that date, if you've not
found anything broken, go ahead and remove it, as even if it /does/ break
something it can't be too critical if you've not used it once in 30 days.

Actually, that isn't entirely the case.  See the Gentoo Handbook, Working
with Portage section, and the ebuild (1 and 5) manpages for some details,
but many Gentoo users have their own local overlays, where they copy
ebuilds and modify them as desired, then redigest and merge them.  I
routinely do this with some packages, say to strip out a filterflags call
that was thrown in by the Gentoo maintainer due to some problem with some
subarchs of x86, where the flags in question work just fine on at least my
amd64, for instance.  That's the beauty of having ebuilds that are
basically bash scripts -- they are easily modified by anyone who knows
bash -- the portage system was deliberately set up to allow this, and a
lot of work has gone into and will continue to go into ensuring that this
easy modifiability remains the case.
