I couldn't get the open-source drivers to work, all I got was a blank 
screen, and that was from fresh install. I had a look at the road map 
for the Xorg drivers and I got the impression that work on the driver 
that supports my cards is far from complete.

The only reason I'm suspecting Catalyst is because those were the 
updates done prior to the panics, and I can't replicate it now.
