--- Comment #4 from Daniel Vetter <daniel at ffwll.ch> ---
Still confused. Another trick to play is to prevent i915 from loading with
i915.modeset=0. Then wait for a while to make sure that we'd catch any lowmem
corruption. Then stop X and reload i915 for real with

# rmmod i915
# modprobe i915 modeset=1

The big question is whether the lowmem corruption happens anyway of whether we
need to load the i915 modeset driver (which would point at either bios
leftovers or a bug in our takeover sequence).
