Public bug reported:

Binary package hint: xserver-xorg-video-intel

Hardware: MacBook 2,1
Running: Karmic amd64

Attaching an external VGA monitor causes X to lock-up (can't change to
VT, black screen except for mouse pointer, which can't be moved) In one
of the crashes, the mouse pointer could be moved, and changed type over
different parts of the screen (e.g. text pointer over console).

Starting X with the VGA monitor attached works, but the monitor can't
re-configured from the start-up settings or it'll probably lock-up.

If the machine is booted with the monitor attached, it will pick up the
correct settings via EDID (eg capable of 1024x768@75), otherwise it only
sees up to 1024x768@60.

After a while, this appears in the kernel log:
