nvidia driver chooses wrong native resolution


I have a GeForce 6600 on an x86_64 Mandriva Linux box, and a Hyundai 32" monitor.
The native resolution is 1360x768. The open-source nv driver works fine at this resolution. However, the nvidia driver ignores my modelines and resolution lines, and defaults to 1280x1024, which is not only wrong, but the wrong aspect ratio, so everything is stretched. 1360x768 is listed in the EDID, so I'm not sure why it's ignoring it. I've also tried deleting the vert/horiz lines, the modelines, and the resolution lines allowing everything to go automatic, with the same result.

This is with 100.14.09 and 9755 builds. Something makes me thing it used to work on an older distro with 8774, but I don't have it anymore.

Any help would be appreciated.

The modes line in the display section have to match the modelines names in the monitor section or else X Window System will fine out the modelines for 1360x768.

more modelines

Well, I think they match enough already. This was generated by XFdrake, and works fine with the nv driver.

If you're implying that I need this line:
ModeLine "1360x768" 84.72 1360 1424 1568 1776 768 769 772 795 -HSync +Vsync
I tried adding it and I still get "no valid modelines".
