nvidia quadro 290 resolutions not detected with sax2

Hi all,

I am running opensuse 11.0 on several computers and I’m using sax2 to automatically configure xorg.conf (sax --auto -r)
Up to now it managed to automatically detect video card resolutions with no problem, but with the nvidia quadro nvs 290 it only detects 800x600, even though both the card and screen can go much higher.
Manually configuring xorg.conf works fine, but I need the auto detect because I am deploying an app on many computers and do not know ahead of time what hardware configuration the computers have.

I am using the binary nvidia driver.
Am I missing something? is this a sax2 problem or the video card?
