Between this and the original error messages, I'm pretty sure that your
driver is broken with respect to texture mapping.
I would switch IDL to software rendering as I noted in my previous post and
start looking for driver fixes.
The only other thing that might be worth doing is to find a really simple
stand-alone OpenGL sample program that does texture mapping and see if that
runs. If it does not, then you have a simple test case that reproduces the
problem which is good to have if you report the problem to Matrox or whoever
is working on the drivers.
