Ok, I see. So the beginning would be to reliably reproduce the the
hang. I have encountered it in any possbile situasjon, both when
watching videos on Youtube and right after booting the machine and
doing absolutely nothing.

I'll try around a little bit and see if I can find something that
triggers this hang.

Btw: which kernel is known to be the "last good one"?

Ilk? If this stands for "Ironlake": I'm on Sandybridge.

Bisecting will be a pain without being able to reproduce
the hang reliably.

Is there anything at the moment I can do to help you to get a grip on
this problem? My machine is a Core i5-420M laptop with 4GB RAM (Asus
U45-JC).
