I have the same problem and was able to locate the cause I think. I'm using two monitors and have the following device section in the xorg.conf.
Section "Device" Identifier "nVidia Corporation G72M [Quadro NVS 110M/GeForce Go 7300]" Driver "nvidia" BusID "PCI:1:0:0" Option "TwinView" "on" Option "TwinViewOrientation" "Clone" Option "MetaModes" "1280x1024, 1280x800" Option "TVOutFormat" "COMPOSITE" #Option "ConnectedMonitor" "TV" EndSection With TwinView "On" the module fails to load and I think it is because it does not recognize the meta modes correctly. (See python failing with a list error below).
