Status with following kernel and userspace stack versions:
Kernel: 3.8.0
Mesa: 9.1.7
xf86-video-ati: compiled for 1.13.3, module version = 7.1.0

The system is more stable again. We had only one kernel freeze and this was
preceeded by a failed GPU reset.

One root cause of the previously increased instability seems to be that the
second X server runs wine-1.4. Wine requires also the 32-bit i386 userspace
drivers, which had to be manually upgraded to the above mentioned latest
versions. 

Is the wine required combined use of 32-bit (i386) and 64-bit (amd64) userspace
drivers on an AMD platform supposed to be valid and stable approach?
