Setting up Dual Monitors on GeForce 6600GT dual DVI card.

I am having a bit of trouble setting up dual monitors on my video card and I think it has something to do with it being dual DVI. I was able to set it up with my Radeon 9800PRO (which had 1 VGA/1 DVI) but I swapped that card for the nvidia because the nvidia drivers are so much better IMO. Also, if I try to set up dual monitors with the GUI, it doesn't let me select my card as a 2nd video card, even though it has 2 DVI ports. in FC3 on my other computer, it lets me select the same video card and it doesn't even have dual monitor support. If someone could help me out I would really appreciate it.

Currently my xorg.conf looks like this:

Currently my xorg.conf looks like this:

Try this for the file after having backed up the original if it does not work can you post the /var/log/Xorg.0.log file so we can see how everything is getting detected copy the file to a backup before restarting the server with the working config otherwise it will be overwritten.
