Mesa provides separate, non-wrapper, vdpau/vaapi/omx drivers. Whether
your is supported or not it's a matter of a trivial test ;-)

In this case - RV710, is R700 generation hardware [1] which should
support MPEG4 AVC and VC1 [2] regardless of the API. I'm leaning that
one should update the table to feature VAAPI [3]. If you spot any
mistakes please update the Archlinux/X.org wiki.
