Well, whatever you do it's better not to install X from tarballs. You can mess
up your system badly, and besides there are 4.3.0 debs available. Try for
deb http://people.debian.org/~ccheney/xfree86/ ./
These are debs for sid. If you want to run woody, then XFree86 v4.1.0 +
xserver-trunk (December 2002) from Michael Daenzer will work fine with Radeon
9000. There is only one little thing you have to change in kdm configuration,
I forgot what it was, but it is explained in the readme file. Add this to
deb http://people.debian.org/~daenzer/dri-trunk/ ./

In my experience for DRM modules to work properly you need either kernel
2.4.22 or an AGP patch for earlier kernels, but this may be related to my
motherboard rather than to the graphic card itself. You also need DRM modules
which come with XFree86 4.3.0 debs or those from Daenzer's repository,
instread of those shiped with linux kernel (you have to compile them, of
course). Both worked fine for me.
