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.
