glx not loading even though the log file shows no errors

[Philip Walden <pwaldenlinux@xxxxxxxxxxx>]

I have an old Nvidia TNT2. I use the "nv" xorg driver. Even though I 
load glx, xdpyinfo and glxgears says its not there.

Looking at the log and conf information below and the fact that I have 
FC4 upgraded from RH9 system, I think that I still have the old 
libglx.so XFree86 module, instead of the Xorg one. If so, I wonder how 
this happened and what I should do to correct it?

Any suggestions welcome.

# glxgears
Xlib:  extension "GLX" missing on display ":0.0".
