Thanks.

I have merged this patch but unfortunately, it does not make the green screen go away.

Neither with our own driver nor with the new one by Hugues (which turned out to not
support SXGA at all but I tried VGA).

I think we should postpone debugging this until Hugues proposed patches are better reviewed.

BR and thanks,
Nikolaus
