Hmm, the opengl driver shouldn't matter on the OpenGL1 backend, unless
there was a bug in their feedback rendering mode. Are you trying to export
the same scene on both systems?

I'd suggest just playing with the export options and see if there's a
solution there. If you keep having trouble, send me a small state file that
reproduces the issue and I'll take a look. There are certain cases where
the gl2ps exporter will fail to capture all of the details in a scene,
though it should produce more than an empty white image.
