8800GT + integrated 6150SE - X server doesn't start

[frostbite]

Hi.

I can't get a 8800gt card to run in Linux on an Asrock NF6G-VSTA motherboard, that has a 6150SE integrated gpu (NForce430). startx fails with "no screens found". X works again if 8800gt is unplugged. Also must be noted that 8800gt card runs perfectly fine in Windows XP on the same machine. I've upgraded to Nvidia Linux drivers 173.14.12 and kernel 2.6.25.11 in hope it might solve the problem, but unfortunately it didn't help. Anything else I can do to make it run?

I'll attach the nvidia-bug-report file. Thanks for any help!
