Probleme ATI 9600 et acceleration 3D

Bonjour à tous,

Je sais que ç'est un sujet qui a déjà été débattu,
mais malgré la lecture de tous les posts
(notamment celui de Doug du 02/07/2004 sur
l'installation des drivers officiels ATI avec
Xorg) et infos diverses glanées avec google, je ne
trouve pas la bonne solution pour activer le DRI
avec ma carte ATI Radeon 9600.

Un mot sur la config :
CPU Athlon 1,2 GHz 512 Mo
kernel 2.6.7-ck1
Carte graphique ATI Radeon 9600
distrib Gentoo
Serveur X : Xorg-6.8.0-r1
Moniteur 19" HP 910 (fonctionne actuellement en
1152x864 75Hz)

Je mets des extraits de xorg.conf, de glxinfo et
de Xorg.log0 (en espèrant ne pas être trop long)

Merci de votre patience et de votre aide.
