Update to a 20050719 snapshot of Mesa, DRM, and now r300 CVS trunk. The r300
support includes all Radeons that I have heard of so far. Requires
xorg-server-snap and DRM from r300 CVS (5.x-7.x DRM insufficient). The r300 DRM
will be committed to -current soon and hopefully merged to 6.x/5.x. Previous
r300 support in 6.x/5.x just results in hangs due to improper command
submission, among other problems.
