Serait-ce un problème de driver ou de X ?

Bonjour,

Je reviens à la charge...
J'ai démarré sur un live CD Sabayon Linux6 / LXDE avec un noyau 2.6.39.

Versions du driver :
Sabayon: 1.10.2
Ocelot : v1.52

Avec la Sabayon, je retrouve un positionnement tout à fait satisfaisant pour ma souris.
J'observe aussi que les traces dans le Xorg.0.log sont plus "complètes".

Traces Ocelot :

Les deux dernières lignes me semblent suspectes
