I load the normals from a lightwave .obj file, and I did in the past
check them to make sure they are of length 1. I'll recheck that again
to make sure they are the right length and point the right way and so
on. I'd expect it to not work on all cards if that was wrong though.

I have no scaling transfoms, only translation and rotation. But I
could turn on the automatic normalisation option in opengl I guess.

Interestingly enough when OpenGL Renderer is: GLX Mesa indirect on a
vmware installation the same problem occurs, this means that there is
something wrong in my code doesn't it? As mesa is doing all the
rendering and not using DRI?
