Similar problem for me on a DELL latitude D620 with an integrated 945GM intel video card (devce ID 8086:27a2). I can only switch (Fn+F8) one or two times to an external monitor or beamer before system hangs completely.
I was desperated, but today, reading a lot of forum posts I tried to uninstall package xserver-xorg-video-intel (and also xserver-xorg-video-all, which is a reverse dependence), and after a X reboot xorg picked up the driver in xserver-xorg-video-i810 package and the hangups are gone!
Just so happy that I wanted to share my experience. Maybe it's useful to others.
