problem DRM-DRI

Bonjour,

j'ai un souci avec mon serveur X qui ne veut pas faire de DRI.
C'est une lfs 5.1.1, sur un athlon je sais plus combien avec
une carte atiragepro128.
Quelques éléments ci-dessous, si quelqu'un y voit une incohérence/erreur
ou s'il a une idée, je prends tout.

Merci d'avance.
