I would like to add my own experience here:I have a g33 based MB with the same problem on Karmic: actually it does not even boot correctly with KMS as it cannot find a screen as it thinks VGA is disconnected. All details (with a patch that forces ddc probing instead of hotplug detection) are here:https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/467841
