Kernel driver does support the VCS ring batches. We should be on par with
the Linux kernel version which was used for the last import.

I never compiled/tested vaapi 965 driver myself. Sure, there may be bugs,
which I think are even inevitable, but VCS engine is quite similar and
simpler then render, so I expect that bugs can be fixed if reported.

Obvious first step is to get libva 965 driver compiling and added to ports.
The sources are available at git://anongit.freedesktop.org/vaapi/intel-driver.
