No sorry (except softpipe) and I'm only testing with r600g, and that
only on an RV710 (some problems have been reported on other chipsets).
There are some people trying R300, but with limited success.

The only thing the va driver currently does is building, nothing else is
tested and/or working, so I won't suggest trying to use it right now.

Yes for XvMC you also need some (small) modifications to the ddx, for
r600 you can find a modified driver here

Try this: export VDPAU_DRIVER=g3dvl

You still need a symlink inside /usr/lib/vdpau to libvdpau_g3dvl.so (or
just place the library manually there). That reminds me that I wanted to
rename the library to match more what's linked inside.
