Just as a status report...
On my thinkpad r50p which has an rv350 (FireGL-T2) when using the
current CVS xorg, CVS Mesa and the tagged r300 driver
'the_perfect_frag') it all works, 1600fps on glxgears, but the
flickering is awful on OpenGL apps...
(Current CVS is yesterday for xorg, today for Mesa).
glxgears - works OK. But flickers. tuxracer - works OK. Reasonable
frame rates. But flickers at about 10Hz. gl-117 - Same. Reasonable
frame rates. But flickers.
glxgears was in a window. tuxracer and gl-117 were full-screen. I
had to stop before I threw up...
Suspend & Resume worked OK so far (Only suspended to RAM once
though).
Hamish.
FWIW the same things also happens on the current CVS copy.
This is with a 1600x1200 resolution LCD as well, just in case it
matters. gl-117 seems to geta round 60fps in the init screens... But I
can't see the screen well enough to navigate through (Or access even)
any setup screens to try & change anything in it.

Flickering should be resolved by adding this to radeon_driver.c in the Xorg:
