Sorry, I got sidetracked while getting a set of logs. However, some (yet
slightly vague) findings may be useful - even if debugging gets maybe
even harder:

Firstly: the computer (BIOS or whatever) behaves differently when
external power is connected or only battery used, and secondly: it
behaves differently depending on the last state of the vgaswitcheroo
BEFORE the reboot. I need to do more testing regarding the former
(probably frequency of crashes higher with external power), but the
latter seemed to me pretty consistently only crashing after "echo OFF >
/sys/kernel/debug/vgaswitcheroo/switch".

I did yesterday a kernel-update to 2.6.38-8, I'll try to reproduce the
findings and will try to see if anything changed in the behaviour.
