No nVidia accelerated video on 7600GS analog output

A few months back, I reported a bug about accelerated video failing on a 7600GS card. Bug was closed as a modeline issue, but I've done further work and have now isolated it to either the nvidia driver or accelerant. Video is OK in VESA mode at all resolutions except 1920x1200 due to a known modeline issue. Video does not work at all when the nvidia driver is invoked.
If there is no /boot/home/config/settings/kernel/drivers/nvidia.settings file, the display does not correctly initialize. Instead, the video output from the analog port toggles on and off. If I copy an nvidia.settings file from an older version, garbage is displayed and the display freezes.
To test further, I built the driver and accelerant with "--target=hrev5" and tested under Zeta. The driver does exactly the same thing under Zeta as under Haiku, so I don't think this is Haiku-specific.
I enabled full logging Haiku with the current driver and under Zeta with an older version that works correctly; I've attached the two log files. I hope this helps.
