Yes. I put in "exit" straight after the #!/bin/bash like and I dont
see it in "ps aux". I also tried to disable DRI in my xorg.conf (which
is otherwise pretty much empty). Neither of these things worked, I
can sometimes survive for 1-2 seconds but in 95% of the cases the
screen starts to flash / blank out before gnome-panel has slided
into place.

I tried the 2.5.96 2d driver now (without upgrading drm/mesa) and
it looks like trunk still has this bug (it freezes as described above).

I only got one machine with intel+intrepid for now so I have no proof.
When I say "modern intel hardware" I mean chipsets like G45, G43, G41 etc
and I suspect all of these currently does not work (but I have only tried
the G45 though, and also only with a specific motherboard).
