Works for me:

00:02.0 VGA compatible controller: Intel Corporation 82Q35 Express
Integrated Graphics Controller (rev 02)

Though I have never seen a 'black screen' problem on this machine. I had
many other i915 driver problems here, though.


There is other thing, though. During the file-system check on boot (I
had quite an uptime here before rebooting) I got:
