Libraries in /usr/X11R6/lib64 but not in /usr/X11R6/lib for the AMD X86-64 cpu

You did not install the 32bit versions of the X libs.

It's certainly surprising that shoving a 64bit library in place of a 32bit 
library actually works; there are probably some hidden bug that will show up 
sooner or later, and bite you in the ass.

FC2 for X86_64 includes both 32bit and 64bit builds of xorg-x11-libs, so I 
expect that FC3 also has both 32bit and 64bit builds.

All you need to do is install the 32bit RPM, and you're all set.

Note that there have been a couple of erratas for xorg-x11, so you should 
simply pull everything from the update channel.
