I may have a solution for you.

Try adding this to the "Screen" section only:
Option "ModeValidation" "NoDFPNativeResolutionCheck"

I noticed that if you put it in the "Device" section it does not work.

Since this forces the driver to use the display modes specified in xorg.conf instead of those it probed via EDID, you should also check that you listed all the resolutions you need in the "Display" subsection.

Here is an example:
Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"
DefaultDepth 24
Option "ModeValidation" "NoDFPNativeResolutionCheck"
#Option "CustomEDID" "/tmp/edid.bin.DFP-0"
SubSection "Display"
Depth 24
Modes "1280x1024" "1280x960" "1280x800" "1152x864" "1024x768" "800x600" "640x480"

EDID in .9629 is acting weird on the GeForce4. Apparently the driver probes the monitor correctly only via the 15 pin VGA connector, while it fails miserably if the same monitor is connected to the digital-VGA connector.

Additionally many of the "EDID" options documented at don't work correctly on the geforce4 (aka "they do nothing most of the time").
