The GPU is the same than on the venerable MacMini on which I tested an 
installation years ago (Debian snapshot 2022-03-28 that had MESA 
22.0.2). I remember I had no more hardware acceleration and the support 
of this generation of GPUs was dropped. Looking at the MESA release 
notes, we can find at https://docs.mesa3d.org/relnotes/22.0.0.html that:

- classic/r100: Delete driver
- classic/r200: Delete driver

I don't know the situation for the Radeon 9600/9700 ...
