I finally managed to get this set of patches tested on the platform that
exhibited the intermittent blanking problem when terminating the Xserver.

I can confirm that Imre's patches resolve the issue and that g4x_fixup_plane()
which I had introduced after extensive experiments is no longer needed to
prevent the blanking from happening.
If you want I can provide a patch to back this out with the appropriate
comments once Imre's patches are in.

Cheers,
	Egbert.
