I have Radeon 9200, using the r200 driver from dri.sourceforge.net. 
The r200 is good enough to play most all games.  r300 works I hear,
but not on my IGP X300.  I do think OS drivers are the way to go so I
hope to help the r300 project out in the the future.

I have no idea on fglrx, never used and don't plan to.

I dunno, it is a legitimate complaint, but it is optional.  I think
the patch requires a registry setting to activate the Opengl depth
conversion stuff.
