I just went through the ATI video driver hell with FC6 after loosing
grub on an update on FC5.  I could not get dual head working in FC6, so
I "down-upgraded" to FC5 where I have it working just fine.  The ATI
Radeon drivers leave something to be desired.  We are having problems
with memory management with them at work, too, in another distribution.
