Blame mesa developers if you hate Gallium:

- Removed the classic Mesa r300 and r600 drivers, which are superseded by 
the gallium drivers for this hardware. 

If you like Gallium build on our mesa-lib with Gallium enabled you'll get:
* r600 driver
* libEGL.so
* openvg
and additional prize:
The Radeon R600g driver is also capable of OpenGL 3.0 / GLSL 1.30 support. 
future improvements:
Video Decode (XvMC/VDPAU/VA-API) on the 3D engine 
(we have all infrastructure in place, just radeon driver needs to advance, 
maybe at 8.1 mesa release). To build your mesa/r600 with XvMC/VDPAU/VA-API 
you need to install these libs first (libXvMC/libvdpau/libva) mesa-lib 
module will detect that they are installed and use them. However 
installing legacy, very limited API like libXvMC makes no sense in my 
opinion as vdpau and libva are much more advanced.

Remeber to export VDPAU_DRIVER=r600 before using VDPAU acceleration.
You can put this export in /etc/profile to have it always system wide.
lin vdpauinfo
If you have all needed hardware/software stuff vdpauinfo should display:
Information string: G3DVL VDPAU Driver Shared Library version 1.0
Decoder capabilities:

-------------------------------------------
MPEG1                16 262144  8192  8192
MPEG2_SIMPLE         16 262144  8192  8192
MPEG2_MAIN           16 262144  8192  8192

This acceleration uses 3D shaders for decoding so expect hot GPU and 
increased power consumption.
