Confirmed on Fujitsu-Siemens S7020 with Intel's i915

Doesn't work with xserver-xorg-video-intel, works with xserver-xorg-video-i810 + 915resolution, although there is heavy amount of flickering and shadows involved when trying to move the window or fullscreening it on a "bad" time. Works perfectly eventually.
