My xorg.conf

When connecting an external monitor via hdmi to my Notebook (HP 8510p with an ATI Radon HD2600 Mobile), xrandr shows me besides HDMI-0 a second output device called DVI-0.
I would not mind about DVI-0, but the problem is, that I have to disable it with "xrandr --output HDMI-0 --off", otherwise HDMI-0 is not fully usable (either a black or a garbled screen).

Attached you hopefully find the needed information. If you want more, tell me.
The driver version I use is the one currently in Debian unstable: 6.12.2

looks like a system that uses router objects.  Can you attach your video bios?

as root:
cd /sys/bus/pci/devices/<pci bus id>/
echo 1 > rom
cat rom > /tmp/hd2600m.rom
echo 0 > rom
