I confirm this bug in nvidia-glx 1.0.8776+2.6.17.6-1 provided in Edgy
final release.
When using 'Add/Remove Applications' to install 'NVidia binary X.Org
driver', the description suggests "to enable the driver, run sudo
nvidia-glx-config enable".
---8<---
# sudo nvidia-glx-config enable
Error: unable to load nvidia kernel driver! Be sure to have installed
the nvidia driver for your running kernel.

Note that both 'linux-restricted-modules-common' and 'linux-restricted-
modules-generic' are installed.
After manually switching the driver from 'nv' to 'nvidia' in
/etc/X11/xorg.conf and restarting X, my BenQ FP731 LCD shows "Out of
range" and nothing comes up. What the video driver fails to display is
the LCD's native 1280x1024. In Dapper I was able to do CTRL+Alt+KP_+/-
and switch to other resolutions as a temporary workaround.
I have 2 solutions to this problem, both involving modification of
xorg.conf:
1. Force a specific refresh rate for the problematic resolution at given
color depth ("1280x1024_75").

2. Disable nVIDIA's handling of frequency ranges.
"By default, the NVIDIA X driver makes use of a display device's EDID, when
available, during construction of its mode pool. The EDID is used as a source
for possible modes, for valid frequency ranges, and for collecting data on the
physical dimensions of the display device for computing the DPI."
