OS: FreeBSD 6-RELEASE
Card: Radeon 7500 RV250. I have also machines with a Radeon R200 card
and a Matrox G200 that haven't worked either with otherwise the exact
same software setups. Again, all of my softtware is built from source
(the FreeBSD ports tree from Feb. 2006).

I am using the DRI drivers that come with Mesa 6.4.1. I have tested
this on all of my machines with different cards, same software, and
they all have the same issue, with pymol only (well I have only tested
with the mesa-demos and VMD but those should be fairly representative
of working OpenGL applications).

Attached are the glxinfo outputs for the radeon and mga cards (with
LIBGL_DEBUG=3Dverbose, as usual).
