I have an ATI 7500 Mobility (in my Vaio), which has working 2D and 3D
acceleration. You do, however, need X 4.2.1 (sarge or sid) rather than X
4.0 (woody). Relevant sections of my XF86Config-4 file are pasted below:
Section "Module"
...
Load "GLcore"
Load "dri"
Load "glx"
EndSection
Section "Device"
Identifier "ATI Radeon Mobility"
Driver "radeon"
Option "AGPMode" "1"
EndSection
Section "DRI"
Mode 0666
EndSection
Make sure you have DRM support enabled in the kernel (the radeon and
agpgart modules). You need to either insert them before you start X, or
compile them directly into the kernel. Also, make sure you have a
/dev/dri file. Finally, this configuration is pretty insecure - it lets
any user write to the DRI device. This is probably okay if you're not
running any external login services, but if you are you want to use
"Mode 0660", and only let users in some group you create (say, "dri")
write to the files in /dev/dri.
HTH.
