The first thing I'd try is to rename /etc/X11/xorg.conf to
xorg.conf.orig, or something like that, then restart X.  This will
let X generate a new config if it needs one, which it may not.  If
that doesn't work, try the following command, as root:

yum reinstall xorg-\*

That will cause yum to re-install all your existing X11 packages.
Any files that the proprietary Radeon driver has clobbered will be
replaced.  (I had to do this a couple of times swapping between
nVidia's drivers and nouveau.)

Hope this helps.
