XServer and JWM on Debian Squezze, problem with graphic driver

Hey guys,

I have installed Whiite Linux with Debian Lenny on my Wii and updated it to Debian 6.0.
I edited the source.list and run a "apt-get dist-upgrade" after "apt-get update". No problems at all.

Then I wanted to install xserver and fluxbox, so I used the following instructions: [forum.wiibrew.org]
Installation was no problem, but I didn't find the xorg.conf. After some research I found out that it is better not to use the xorg.conf, because newer xservers can run good without it.

Ok I tested to start the xserver with "startx /usr/bin/jwm", get no errors but a green screen and a part of the JWM menu bar, screen size wasn't right. So I decided to use a xorg.conf, but the creation failed with the error:

Xorg: symbol lookup error: /usr/lib/xorg/modules/drivers/cube_drv.so: undefined symbol: LoaderRefSymLists

I created it manually and tried to start the xserver again, but then the same error:

/usr/bin/X: symbol lookup error: /usr/lib/xorg/modules/drivers/cube_drv.so: undefined symbol: LoaderRefSymLists

I think the driver is outdated. Can someone help me and know how to deal with this?

Greetings, Strece
