I didn't test with Mesa 3.0. I'm focused on Mesa 3.2 and 3.3 now and
don't have time to go back and fix many bugs in 3.0.
One thing you should probably do is glEnable(GL_NORMALIZE). Otherwise,
your glScale(1,1,0.1) call is causing your normal vectors to be non-
unit length. That messes up lighting.
I tested this change with Mesa 3.1 and it looked good.

Move your glLightfv() call before your rotate and translate calls.
