Radeon R5xx 3D programming guide released

From the page you linked to:(http://wiki.x.org/wiki/radeonhd#head-cc89624fd96105127892119323e209b3d80e137d)

The following subsystems have not been implemented yet or show some limitations:

• No 2D and 3D acceleration so far. No XVideo (needs 3D engine for scaling). Still, fullscreen video is working fluently for many users.
• No TV, Component, and HDMI connector support so far.
• No Dual Link DVI support so far.
• Panels only show native resolution.
• No RandR rotation support so far.

Suspend & Resume is pretty much untested. Often it just works, but your mileage may vary.

In other words, currently it seems to be little more than a dumb framebuffer. Hopefully now that documents have been released, this changes for the better. I wish I could help, but I lost the track in video hardware programming about the time VGA came along...

Yes, this is just in the radeonhd driver.  The mainline radeon driver supports textured video,
2D and some minimal Render acceleration for everything up to r5xx, as well as dual-link DVI
and scaling for LVDS.

Hmm, that render acceleration for the R500 only applies to EXA, doesn't it? I certainly saw no
evidence of render acceleration being enabled with XAA. (And I did check the Xorg.0.log file.)

Yup, "no text here".

All X drivers are transitioning to using EXA exclusively; the only reason I know of to stick
with XAA is if your card's EXA support is less stable than the older XAA support.

That is unlikely to be the case when using brand-new drivers for previously unsupported
hardware :-).  I'd just turn on EXA.  (And if things break, then file bugs and maybe drop back
to unaccelerated mode, I guess.)
