No idea, I just remember seeing a discussion of using a single large framebuffer for both viewports and then setting up the card to send a portion out each interface, so you would get the same hardware acceleration on both screens. It only worked for cards with 2 outputs, i.e. not multiple cards, and I can't remember which cards they were talking about.
