Admittedly, the answer is hidden in the Debian changelog:
,----
| xserver-xorg-video-intel (2:2.12.0+shadow-1) unstable; urgency=low

| * Don't enable DRI2 if the shadow option is on.

Option "Shadow" "False"
in this section would disable the shadowfb and enable dri2, at the risk
of running into GPU lockups the 8xx chips are so notorious for. See the
changelog snippet above for Debian bugs that you may encounter if you do
that. Looking at <201008150200.52677.jrvp@bordenrhodes.com> from
August, they may very well have happened on your system in the past.
