On every boot, as soon as I login and compiz tries to start, the above message shows up in dmesg.

You need to update the dmc firmware:

Same happens with 1.04. Attaching dmesg, /sys/class/drm/card0/error.
Also, echo 1 > /sys/kernel/debug/dri/0/i915_wedged doesn't seem to have any effect, it's still unable to reset the GPU.
