Apps launched with vdpau enabled produce the error: VDPAU_DRIVER=r600 vdpauinfo or mplayer ...
I also see this on recently built linux from scratch systems - I don't see it with the same vdpau/mesa etc on older systems, so I guess something got more verbose/fussy.
Doesn't seem to affect functionality and I can also produce with
VDPAU_DRIVER=softpipe vdpauinfo
so not just r600g.
