There is a problem with xorg-6.8.2 and certain ATI cards.  The problem
is upstream though.

https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=170008

This issue is more prevalent on 64-bit machines ... but it probably also
happens on many RADEON cards and on all arches.

Pasi Pirhonen (our ia64, alpha, s390(x), sparc guy :) saw this problem
early on, and has developed a fix that works ... but RH now has it for
action.

In the meantime, if you remark out the load DRI line
in /etc/X11/xorg.conf, it should fix this specific issue.
