Default G210m Blank Laptop Display

I just recently got a Sony Vaio laptop which has a G210M graphics card.

After installing various versions of the driver, both production (185.18.36) and the latest beta I could find (190.42), and setting up X to use the 'nvidia' driver, the laptop display goes blank and actually turns off when X starts.

After a few hours of googling and trying things, I believe that it's incorrectly detecting that no monitors are attached and it's trying to display through the vga port.

Including Option "ConnectedMonitor" "DFP" causes the screen to come on at least, but it's just grey and back lines. I would guess that it's a resolution problem at that point but I'm not sure where to go from there.

I've tried generating some mode lines but I can't even get one for the native resolution (1366x768) and 1280x720 didn't work either.

Any ideas?
