[ltp] 3d acceleration, debian/unstable, T41 (radeon 7500)

[Atte André Jensen]

Hi

On my T41 I have two partitions one running debian/stable (where 3d
acceleration works fine) and one that I just installed running
debian/unstable (where 3d acceleration doesn't work). I use the same
xorg.conf file (which btw is here http://atte.dk/download/xorg.conf) on
both installations, so something els must be different. Could it be that
I forgot to install a certain package under unstable? Any ideas? Anyone
running debian/unstable with 3d acceleration on radeon 7500? Here's some 
info:

atte@ajstrup:~$ lspci | grep Rad

and/or errors above for possible reasons

Regarding the last one: the warnings are (and they are exactly the same 
under stable, where 3d accel works):
(WW) open /dev/fb0: No such file or directory
(WW) open /dev/fb1: No such file or directory
(WW) open /dev/fb2: No such file or directory
