nvidia module/xorg/EDID issue

[Stuart Young]

Hardware: Toshiba Satellite P20. nVidia GeForce FX Go 5200, LCD res: 1440x900

Problem: Once nvidia-glx is installed and enabled (nvidia), Xorg doesn't find
the correct resolution for the LCD on this machine. Without nvidia-glx enabled
(nv), Xorg produces usable display.

Xorg.0.log reports:
 (II) NVIDIA(0): Not using default mode "1440x900" (hsync out of range)
 (II) NVIDIA(0): Not using mode "1440x900" (no mode of this name)

Looking above shows that EDID is reducing hsync to 29-55 kHz

Disabling EDID (Option "IgnoreEDID") and setting hsync to 29-57 kHz ("HorizSync
29-57") gives usable output, and results in the following in Xorg.0.log:
 (**) NVIDIA(0): Default mode "1440x900": 108.8 MHz, 56.9 kHz, 60.2 Hz

Discussed with daniels on IRC: Looks like some sort of rounding issue or
something weird with EDID.

Have punted this upstream to the nvidia guys.
