It looks like one of these patches fixes the crash of the X server on my
machine (applied on v2.6.25 release):
http://lkml.org/lkml/2008/4/19/244
http://lkml.org/lkml/2008/4/19/243

Also system load seems to be lower. The only problem is that the X server
heavily crashes on shutdown (resp. when executing /etc/init.d/gdm stop)
now. Even the console gets corrupted. I attached the kernel log file that
shows the kernel oopses.
