(II) RADEON(0): Port2: XRANDR name: DVI-0 Connector: DVI-I DFP2: INTERNAL_KLDSCP_DVO1 DDC reg: 0x7e50 Your system uses DVO for the DVI port rather than one of the internal TMDS transmitters. I think this is the first system I've seen like that. I may need to add some additional code to make that work. Can you send me a copy of your video bios?
