The screenshot looks like a memory problem, since it's not hardware it 
could be a bug in the driver (something's writing to wrong mem 
locations/corrupting it?)

Xorg.conf seems ok, have you tried using only Ati dual displays and not 
using the nvidia card/driver, maybe we can narrow it down to a problem 
between the two drivers.

good luck :)
