I should have said this bit applies to the Radeon HD 3850 and other recent
cards. 3d support for older cards goes much further back.

No, Radeon has for some time fully supported 2d and 3d for r100 to r500; that
is Radeon 7000 through 9000 series and x300 through x1950. Radeon HD 2xxx
through Radeon HD 4xxx (r600 - r700) have more limited support at this time.
All the specs for these have been released, but even with specs it takes time
to make the drivers.
For really old cards - Rage and Mach - documents have not been freely released,
but 3d support was developed with docs provided to specific developers under
NDA (predating AMD's 100% open attitude).
