I agree Duncan.

Now, the one issue left for complete world domination would be to
better understand how to get DRI working with this video adapter. Am I
correct that DRI==3D? Or does DRI go further than just basic 3D and
help other things like MythTV or something else I'm not thinking of at
all?

I do see these messages in xorg.0.log:

(**) RADEON(0): RADEONSaveMode returns 0x709390
(WW) RADEON(0): Enabling DRM support

        *** Direct rendering support is highly experimental for Radeon 9500
        *** and newer cards. The 3d mesa driver is not provided in this tree.
        *** A very experimental (and incomplete) version is available
from Mesa CVS.
        *** Additional information can be found on http://r300.sourceforge.net

drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is 6, (OK)

I do NOT do ANY Linux-based 3D stuff today. My workload is Mainly
music applications - Ardour, etc., which do not care about 3D, web
browsing, MythTV and Xine to watch movies.  Do I / should I care about
DRI?

I do occasionally play Windows games under Cedega. Would DRI ever help
that sort of application?

Anyway, things seem to be in pretty good shape. Maybe I should just
leave good enough alone. ;-)

Cheers,
Mark

P.S. - I'm still curious about trying your compiler flags but now
there is no pressing timeframe to do it in on this machine. - MWK
