This would be a great and welcome contribution!

libtheora doesn't currently use intrinsics, but that's ok. If you provide
a patch with intrinsics that can speed up libtheora, I'm sure it will be
accepted, even if the maintainers decide to recode it as inline assembly.

Converting it to SSE2 would be interesting.

I don't think so.

Sounds good to me!
