Problems with GL_ARB_multitexture extension on the Geforce3 (LOD Fading)

Hello,

I sent a question to this mailing list a few weeks ago asking if the
Geforce2 supported LOD fading. I recieved a reply, telling me that the
Geforce2 doesn't support the required extension (I think it was
GLX_ARB_multisample).

So, we have just invested in a Geforce 3 ti500 card to run our Performer
based applications. Unfortunatly, LOD fading (and anti-aliasing) still
dont work. Is there any modifications that we need to make to our
software?

We are using beta 2 of version 2.5 of performer for Linux and version
1.0-1541 smp Geforce drivers.

The glxinfo output is as follows:
