These patches solve the problems with severe screen flickering I
experienced on a "Mobile 4 Series Chipset" (rev07) and bisected down
to the "drm/i915: framebuffer compression for GM45+" commit
(74dff282237).

The flickering was most easily triggered by closing and opening the lid,
and was reduced or temporarily stopped by moving the mouse or pressing a
key.
