That is the model computer that I had trouble with. I thought that this 
was stuck at 640x480 before the BIOS upgrade to A04.

Since you have the same model computer. I was wondering if the FC2 newer 
  versions of X have reduced a random lockup with certain screensavers. 
I moved up to test distros on this computer and do not have the random 
crashing as with FC2 before the CVS xorg-x11 releases.
Since the radeon 7000 problem surfaced with the upgrades, I was 
wondering if some of the CVS changes were backported to the latest 
server upgrade.
