Well, I guess that if the fog were insanely dense, you'd
see just a plain screen.  It's interesting that you have
problems with TuxRacer (which is not using PLIB or any of
my code - so it's unlikely to share the same set of bugs
as TuxKart and TuxAQFH might).

Can you dive into the Tux/TuxKart source and change
the glEnable(GL_FOG) call(s) to glDisable(GL_FOG) ??
That'll prove or disprove the Fog theory.

You could also try the handful of SSG example programs that
are available on the PLIB website.  Be sure to get the
version 1.2.0 examples though (presumably you have PLIB
1.2.0).

Hmmm - the menu bar has some kind of 'texture' to it.
That's very strange - it's supposed to be just plain.

The plan-view of the track is all broken up...like it
has been somehow textured in the same way as the TuxAQFH
menu?!?

There is certainly something VERY sick here...but I'm
at a loss to know what it could be.  It might be worth
posting this issue to the Mesa list - clearly the fog
problems you see in TuxRacer indicate that not all of
the problems are unique to my code.  Perhaps there is
some kind of a Mesa problem that affects both programs
but in different ways.

TuxAQFH and TuxKart have both run correctly on dozens
of different OpenGL drivers and cards - so I'd be quite
suprised if this really was a PLIB or TuxAQFH/TuxKart
problem.
