MGA can do deinterlacing in hardware according to the docs, but it's
not implemented in mga_vid driver right now. I might work on adding
support for it sometime, especially if anyone else is interested. This
would of course mean realtime deinterlacing with no cpu cost, but I
think it might make triple buffering difficult or impossible (=>
shearing) so I'm not sure if it's worthwhile.
