Ok, these corruption does not seem to appear when I disabled compositing by
pressing Alt-Shift-F12 on display :0 and shortly after I start the second KDE
session on display :1 as well. So this seems to be related to having to
instances of Radeon KMS X.org displays running at the same time.

Since I already tried with :1 without compositing, it might be sufficient, when
:0 runs without compositing. I try with :0 without and :1 with compositing
after I am confident that both without compositing run stable.

Bug 23622 -  probably radeon kms / memory shortage related scheduling while
atomic

might be related to this one.

I will also compile a 2.6.37-rc3 and test it as well.
