Etienne,
You are experiencing a problem with the 3.3.6 Xfree drivers from nvidia. I
had to step back from that version to get this to work(texture problems). I
have since then stepped ahead to Xfree 4.0 and the beta .93 driver and all
is well. Check out www.nvidia.com for latest drivers. Good Luck.
Rob
