Can you try with xserver-xorg-video-intel 2.2.99.903 from experimental?

Could you try catching  better backtrace with gdb after installing
xserver-xorg-video-intel-dbg ?
Just attach gdb through ssh from another machine with
    gdb -p $(pidof X)
then reproduce the crash, enter 'bt full' in gdb and send us the output.
