I'm seeing this too on an EeePC 900 with an intel i915 card. The problem is reproducible every time (just doing something like xranr --auto with the external monitor plugged in triggers it for me). Interestingly if I use a 2.6.32-rc kernel then I am still able to switch VTs (which I am not able to do with a 2.6.31 kernel) but dmesg is filled with the following:

[drm:i915_gem_execbuffer] *ERROR* Execbuf while wedged

From then on Xorg will not display a picture even if gdm is restarted.
