ati mobility radeon x600 pci-e / black screen

[Martin Jordan <fanti at spin dot de>]

hello,

i've a samsung x20 1600-2 notebook with an ati mobility radeon x600 
(pci-express, 64mb memory) graphics chip and i want to get it work with 
xfree86.

so i followed the instructions from:
http://www.stanchina.net/~flavio/debian/fglrx-installer.html

i'm running debian/unstable (kernel 2.6.11.5). the kernel module compiled 
after applying both patches with 2.6.11.5.

everything seems fine so far but each time i'm going to start x the display 
turns black and that's it. the x-server runs but the screen doesn't come up 
and stays black (also with any resolution "dpkg-reconfigure xserver-xfree86" 
can setup by default).

the xfree86-log:

xfree86-config:
http://fanti.staff.spin.de/XF86Config-4

kernel-config:
http://fanti.staff.spin.de/config2.6.11.5

lspci -v output:
=========

i've no idea what's wrong here. thanks in advance for any help.
