+ i945 (dell d430) karmic randomly stops updating display and responding to keyboard/mouse

** Description changed:

  Since upgrading to karmic I am experiencing regular, random, hard

- to trigger suspend/resume don't work, hitting the power button doesn't
- either (triggers a disk read, but doesn't pop up the dialog). I haven't

- arenon-functional as well.
