                    bits error when starting the X server

Xorg.0.log

I am running Nouveau on a Dell Latitude C840 with an NVIDIA GeForce 4 440 Go
which has 64MB of VRAM and AGP 4x. I am the unlucky owner of a C840 with a
Samsung LCD that needs a hacked EDID to work properly with the nvidia driver
(attached). My Linux kernel version is 2.6.24.1 and I am running Debian Testing
(Lenny).

Nouveau was compiled on 02/13/08 (today), and I removed the nvidia driver
before installing it.

I get this after enabling randr-1.2 support in the output of startx when it
starts the X server:

Raw DCB entry 0: 03000223 00000004
(EE) NOUVEAU(0): Unknown LVDS configuration bits, please report

The X server fails to start because there are no valid video modes to pick
from, so all the screens have a invalid configuration. Attached is a detailed
Xorg log file that details the register dumps.

lspci | grep -i vga:

01:00.0 VGA compatible controller: nVidia Corporation NV17 [GeForce4 440 Go]
