Cannot get X.Org to start in 75Hz

[frase]

Running FreeBSD 7.0 RC1, nvidia driver 169.04, X.Org 7.3 (server 1.4.0).
The monitor is a Samsung 940BW and the GPU is an 8800GT.

For some time I have been unable to start X at a refresh rate of 75Hz, although it used to work fine. I can also set the refresh rate manually using nvidia-settings. Anyhow, I'll post my xorg.conf in the hope that someone will be able to tell me what the problem is...

Please start X with the -logverbose 6 command line option and then generate/attach an nvidia-bug-report.log file.
