ati radeon 9700M and X

[Tim Taubert <ttmails@gmx.de>]

i have a problem.. in order to get 3d acceleration on linux laptop 
working i downloaded to newest driver from ati.com.. for xfree 4.3.0...
driver version is 3.11.1

i followed the instructions of several how-tos and the driver loads and 
when i start kdm and log in it all works...
i don't know if 3d acceleration works.. i think so? at least fglrxinfo 
said that the renderer is the radeon card...

the problem is that when i want to switch to console the system hangs 
and some stripes are visible...
the same problem when i want to logout.. it even hangs when i want to 
switch to console when i'm not logged into kde..
the whole system crashed.. every time i tried and there's no way to 
shutdown correctly.. not even via ssh server..
the system freezed completely..

are there any settings to be made in /etc/X11/XFree86-4?
and don't ask me for any logs... i looked into the xfree, kdm and 
xserver log.. the crash is not logged anywhere..

i hope anybody can help me!
thanks in advance!
