------- Additional Comments From [EMAIL PROTECTED] 2006-09-14 08:39 -------
I forgot to mention that I patched mesa to disable some software fallbacks for
smooth shading.
There's a comment in r300_render.c that says that the hardware doesn't appear to
support smooth line shading. However, I have seen it work, so I believe that to
be incorrect, at least for my hardware.
Here's the mesa patch, from phoronix's gentoo overlay:
