Can you please try my ppgtt branch from my fdo repo at
http://cgit.freedesktop.org/~danvet/drm/ ? Note thought that it'll
only work on snb/ivb and that suspend/resume is broken. Also, it won't
properly re-enable ppgtt when resetting the gpu after a hang.
But testing feedback highly appreciated.

Thanks, Daniel
