Also, check the driver for that Radeon card. Is it the one that is
specifically for that card and enables the 3D rendering or just a
"generic" one?

It's the OS fglrx driver. I think it may be the generic OS Radeon
driver. It allows 3D direct rendering with AIGLX.

Well, does it say in /etc/X11/xorg.conf

Driver "radeon"

or

Driver "fglrx"

or something else? Just "grep Driver /etc/X11/xorg.conf".

Hmm, a good indicator of 3D acceleration is to run

glxgears -printfps

With software 3D, you get something like 200fps, with hardware
acceleration significantly more.

You can also post the results of

egrep -i "glx|drm" /var/log/Xorg.0.log

On a Mobility Radeon 9200 machine with 3D acceleration this gives:
