X11 is mainly working, sometimes it is hanging (i.e. I can move the mouse
pointer, but I can't activate any window or menu, but I can switch to
console
to restart gdm) sometimes it is hanging, that only the powerswitch helps,
sometimes the screenserver hinders me continue to work (because there is no
window to enter the password, and to enter id blindly do not help either).

--- Comment #1 from Ilia Mirkin <imirkin at alum.mit.edu> ---
Please upload your VBIOS (/sys/kernel/debug/dri/0/vbios.rom). Also, is anything
connected to VGA-1? If not, does such a port actually exist on your device? If
so, can you check what happens if you do plug something into it?

Also please supply a copy of your dmesg shortly after boot (i.e. before those
messages overflow your kernel log)
