It's on my latop (MSI S260) with a Intel GMA900 chipset (that's the newer Intel onboard chipset). So it's no ATI or NVidia chip, if that matters.
The drivers are the default drivers for xorg, all this is on Linux (Ubuntu Hoary). (Actually I was a bit surprised that it works at all on a non-NVidia card. Should this work on "all" OpenGL cards, maybe even my old Matrox G450?)
i think the shader-implementation you are using is implemented in mesa, so it should work on any card. (the example uses ARB-shaders not nvidia-specific ones) however, it might be slow...
i'll go and try to find a machine with mesaGL instead of nvidia's drivers to check...
