OK, so it looks like you have everything set up right... But you don't 
seem to have any acceleration.  That's bizarre.  10 fps is what I would 
expect if I was using the nv driver....

You have a single head, right?

OK, looking back at the xorg.conf file:

In Section Module, take out

    Load           "glx"
    Load           "int10"
    Load           "vnc"
    Load           "vbe"

and remove the last Composite section.

Restart gdm (or whatever you use) and try it again.
