Question 1.0-9629 uses 75Hz instead of 60Hz

I got a new LCD monitor (Dell 1907FP) and tried to use it with my system here. The graphic card (GeForce2 MX/MX 400) insists on using 75Hz instead of the desired 60Hz. This phenomen disappeared by using an older version of the nvidia driver (1.0-8774) and/or by using the open source nv-driver.
Is there a way to force the card to use the 60Hz?
I allready modified the edid file with a hex editor to cut off "1280×1024@75 Hz" and disable the modes from Vesa and from X-server. But this was not enough. The image on the screen is the same as with 75Hz but the monitor "says" the frequency is 60Hz.

Here are a few parts of the Xorg.0.log
