So the good news is that I managed to get a newer version of the linux
mesa drivers built (on another machien) and running. The bad news is
that if I disable the fallback for smooth line (either be enabling
disable_lowimpact in my .drirc file or by commenting out the fallback in
the r300 source code), I get a kernel crash:

As you can see, I'm using the DRM drivers from git, but it also happens
with the -CURRENT drm drivers.
