karmic gdm restarts X infinitely when video driver fails to load

Bug description:
Binary package hint: gdm
If Xorg is misconfigured in a way that prevents the video driver from
loading, such as this /etc/X11/xorg.conf:
Section "Device"
Identifier "Default Device"
Driver "drunk"
EndSection
(or, more realistically, if you’re using a proprietary driver that
failed to compile for the current kernel), then gdm will respawn X
repeatedly, many times per second, forever.
When this happens, it is nearly impossible to log into the console to
stop gdm, because you cannot tell which characters of your password
made it into the password prompt while the screen was flickering
wildly. So if you want to test this, make sure you have an open
console root shell with ‘stop gdm’ ready to execute.
