Hi, I am using the open source drivers , radeon and radeonhd. When I try it on a similar board with AMI bios , xrandr can switch on the HDMI port without any problems - with radeon and radeonhd. I guess I could give Catalyst a try to see if it makes any difference(maybe it does magic with the vga bios) I think however, that the problem lies in the fact that some config needs to be done in PCIE-GFX , so that one of the ports gets configured as TMDS. Right now, I am trying to get that to work - so far no results yet .... Another interesting fact is that I am working with this board that does not have another BIOS except for coreboot .... so I have nothing to compare register values with.
