I use 2 crt monitors (2 screens on a display) and GeForce 7100 GS.
Workarounds: Not use the other monitor (comment out the Screen 1 "Screen1" RightOf "Screen0" -line) or downgrade nvidia drivers to 260.19.44.
256MB for 2 screens is a much to low.
You could barely make it to work if you disable COMPOSITE extension and don't use any desktop effects.
I did it to open second screen on my one monitor in order to play movies seamless with VDPAU in 1920x1080 mode with desktop in 1920x1080 mode so it is possible to do.
