but fc9, kernel 2.6.26.1, nv driver 173.14.12 works well on my laptop:dell m6300 with fx3600M, I don't have two graphic cards on the laptop though.

The server seems to be having trouble picking one of the GPUs.
Try adding:

BusID "1:0:0"

, or if that doesn't work then:

BusID "2:0:0"

to your Device section to pick one manually.

Hmm thats a strange one,

I had dual FX 5600 quadros working in both sli and unpaired on an older kernel.
