Bug description:
  I run Oneiric alpha 2 64+mac live CD. Plugging in an external monitor
  with a DVI cable causes the screen corruption.

  The laptop's main screen splits into two halves. The top one keeps
  showing whatever it was showing when the monitor was plugged.

  The bottom half displays properly.

  The external monitor is fully black except for the menu bar at the
  top.

  Unplugging the monitor makes everything work again.

  Using a VGA cable gives almost the same results, except that the split
  does not happen at the middle of the screen but rather about a quarter
  from the top. The top also displays black rather than what was there
  originally.
