ok..
mi era sfuggito.. pare che la mia domanda sia un FaQ


Question 4.35: 3D acceleration doesn't work after enabling the new
Composite extension in Xorg
At the moment, the driver will automatically disable direct rendering if
you enable the Composite extension. This will be noted in your
/var/log/Xorg.0.log file with a line like this:

   (II) fglrx(0): Composite extension enabled, disabling direct rendering

To get 3D acceleration back, simply comment or remove the line in your
xorg.conf that loads the Composite extension.

a quanto pare Ati non supporta quest'estensione.. magari con i nuovi
driver... mah
