3D acceleration exists for r[12]xx and r250; I'm not sure whether it
exists for the rv280. Indeed, it's in the stock XFree86 4.3 debs
previously distributed by myself, now distributed by the XSF.

The r3xx series is currently only supported (in both 2D and 3D form) by
ATI's binary drivers. However, ATI have a standing offer of specs,
hardware and developer access to any DRI developer who wants to write a
driver for the r3xx series.

Binary-only drivers are best avoided, but when you have no other option,
sure.

Uhh, that's utterly incorrect. My Radeon 9000 has out-of-the-box 3D
support, as do original Radeons, and all Radeon 7xxx, 8xxx, and 9[01]00
cards. The 9200 *may*, but I'm unsure. Hell, GATOS will even give you
VIVO support. The reason why you only get FireGL drivers is because you
don't *need* those drivers for the cards I mentioned above.

As for support, I've had pretty amazing support from ATI. ATI have
developer contacts who regularly feed patches into XFree86 upstream and
packagers (the entire 030 patch series was sent through ATI), and they
have the standing offer I mentioned above. The only thing preventing
capital-F-Free drivers being written right now is DRI developer time
constraints, AIUI.

nVidia have never offered any such deals to developers, or Free drivers
(the current ATI driver was originally donated by ... yep, them - ATI).

I personally buy ATI because not only are they currently the best card
around (even when wrapped in OpenGL, the demo optimized for nVidia
cards, by nVidia, to show off nVidia cards, runs over 15% faster on the
9800 Pro than the GeForce FX, and the 9800 Pro has been out longer than
the FX. Not only that, but ATI have offered outstanding support to
XFree86, and I can do my acceleration with a Free driver, not needing to
depend on nVidia to fix my bugs, or make the kernel module not use up
1mb RSS, or whatever.

Daniel, happily with his Freely out-of-the-box 3D-accelerated r250.
