Yeah, we most likely also want to use the newest VCE firmware supported 
for SI here and not the old one we used for radeon.

Unfortunately the VCE firmware interface wasn't backward compatible till 
recently. So the new firmware won't work with radeon any more.

Ok please send out a complete set of patches. I will ask around on 
Monday how we can support this work.

Thanks,
Christian.
