Default NVIDIA Dual Monitor Setup On Debian

Hi,

I'm having issues getting my triple head setup on debian.

Debian Lenny
Driver Version: 173.14.09
Card: 2 x GeForce 7600GS
Monitor: 3 x Dell 2007FP

I've managed to get it working by reducing the resolutions on the Twinview screen to 1280x1024 for both screens. However If I increase it to 1600x1200, the first screen goes to 1280x1024 and the second goes to 800x600. Notable lines from the Xorg.log

I've had to set the second monitor up using a vga->dvi converter, if I have both connected via DVI to the card, it fails to detect the second screen, it does it on both cards. The screen on the second card works fine.
