You did install both the DRM and DRI driver from r300.sf.net CVS, right?
I was wrong about our kernel DRM really supporting r300 -- the
development is now happening in their CVS, until they get things
stabilized.

This patch should be sent to r300.sf.net folks once you get it working,
assuming they don't already have it in their CVS.

http://dri.sourceforge.net/cgi-bin/moin.cgi/DriTroubleshooting  has
instructions on troubleshooting DRI issues.

Render acceleration is about the 2d Render extension.  It's totally
unrelated.
