To work with multihead, you'd have to have some sort of dispatch lib that would optimally divide, or just dispatch the data to the appropriate head's renderer. the DRI would need something similar. If you solve the problem once you could solve it twice and fix both. Still, it seems like a lot of work. I didn't fully realize how XvMC worked.
