Damn babelfish, I was going to use falsch, but I wanted to sound more
sophisticated.

This indicates to me that the BIOS isn't initializing the card, perhaps we
can get X to do this for you.

You may still want to try changing slots, it couldn't hurt. If you read
the link I sent you, you will see that the some BIOSes make assumptions
about the cards by their position on the bus. Perhaps the BIOS assumes
any PCI video card in slot 11 is the primary.

What happens when you boot ohne X? Run level 3, vielicht?

Alles klar.
Is there anything interesting the the /var/log/Xorg.* logs?
