Mhm, unfortunately not really. VCE has some interactions with the 
display path for frame grabbing, but as far as I know we haven't 
implemented any of that.

Maybe patch #9 has some relation with that. Does it work when you only 
leave the VRAM at the location programmed by the BIOS but keep the rest?

Anyway in the meantime patch #1 is Reviewed-by: Christian König 
<christian.koenig at amd.com> and patches #10 and #11 are Acked-by: 
Christian König <christian.koenig at amd.com>.

Regards,
Christian.
