On my old X300 card the driver detect 2 DVI ports but the card only has one. It also think my monitor is connected to both. I can turn off one of the outputs using xrandr and then everything seem to work as it should after that.

I use fedora and it didn't use to be like this. The problem is at least in both fedora 8 and fedora 9. It did work in fedora 6 and I don't know about fedora 7.

Can you send me your bios?

as root:

cd /sys/bus/pci/devices/<pci slot>/
echo 1 > rom
cat rom > /tmp/rom
echo 0 > rom

you can find the pci slot from lspci:
01:05.0 VGA compatible controller: ATI Technologies ...
^^^^^^^ slot id
so:
/sys/bus/pci/devices/0000:01:05.0/
