I've been having a lot of trouble with the radeon driver also.

https://bugs.freedesktop.org/show_bug.cgi?id=2556
and
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=150973

My only progress was to download and replace versions of the ati and 
radeon drivers from a particular website menioned in the bug reports and 
X worked excellent comparative to the drivers in the FC rpm binary 
packages or when compiled again. I also compiled the src.rpms with the 
same results. (crashes, lockups and other problems.)

I also pulled in from cvs the source and performed a make World followed 
by a "make install" and the performance/failures were the same. The 
difference noted between the CVS compiled version (locally) and the 
binary version from the FC repositories left the FC version way ahead in 
reference to performance. so I assume that something is being broken 
when compiling with FC either by the developers or a do-it-yourself 
compilation.
The binaries added to either prevented the screen from bombing and they 
were compiled from neither an RH build system or on an FC users system. 
Why they in fireign binary form and not on FC baffles me.

File a bug report for either freedesk.org and/or bugzilla.redhat.com 
that comes close to the solution. For going back to an earlier xorg-x11 
version, see below.


  The problem remains. So, I'm thinking that I should

Download all the xorg related rpms into a local directory and then run 
the command below from within this directory where you placed the rpms.

rpm -Uvh *.rpm --oldpackage

while you are root and preferably you are out of X and in a terminal. 
This should replace the new packages with the older versions. If you 
find that there are additional programs/libraries that also need to be 
rolled back, place these rpms within this directory and repeat the 
command above again.

I would *not* advice rpm -e or yum erase for going back in X versioning.

Good luck,

Jim
