[Xorg-driver-geode] BUG: AMD Geode driver fails on AMD Geode A830 board complaining about Modes

[Néstor Amigo Cairo]

Hello!!
I have a problem, probably a bug, using AMD Geode X.org Driver v.2.7.7.6
on X.org Server v1.1 (X.org 7.1), Debian Etch (stable) 32bits.
I have a A830 motherboard, with AMD GeodeLX-based 5536 Chipset and
GeodeGX processor (so GX processor on LX board, but works fine). The
board has a 800x600 CRT panel attached to the Motherboard. Everything
works fine with vesa driver.

The problem is that when I configure xorg.conf with AMD driver:

[...]
Driver "amd"
[...]

And I try to start X.org, using xinit, I get the following error
message:

(EE) AMD(0): No valid modes were found
(EE) Screen(s) found, but none have a usable configuration.

What's wrong with it??

I suspect that it does not detect the Display properly.
