Any luck with this dthrock?
I have the same problem with an Nvidia 8400GS, but I am using a VGA connection.
If I change the "Driver" in my xorg.conf to vesa it works. (in UI1 onyl). Once I change it back to the nvidia driver all I get is a black screen.
Exactly the same issue we had with our cards, although I find it surprising you should be having the issue with a VGA connection (my problem was with SVideo). Simply turning on UseEDID may be your solution - you'll see the option turned off if you go through the file. Below are a number of options that may be significant - compare with yours and make changes as necessary:
Section "Device"
Driver "nvidia"
Option "UseDisplayDevice" "CRT"
Option "renderAccel" "true"
Option "UseEDID" "true"
Best Regards,

If that doesn't work try tweaking your refreshrates or modelines in the xorg.conf manually.
