The saga continues.  I hope I don't develop the same reputation as Karl 
L. ;-)

Even though I removed the fan from the ATI graphics card, a friend 
suggested I drop back to the standard VESA VGA X driver and see if that 
worked.  It did.  Even with screen savers and OpenGL applications the X 
server did not freeze.

Should I post a fedora bugzilla report for the ATI driver?

I have xorg-x11-drv-ati-6.7.197-1.fc8 loaded.
