Yeah, these days card do stereo either : - by using each output for a separate viewpoint - by doubling the framerate (for example displaying at 120hz but alternating 2*60hz). Although the latter requires hardware (or as you mention detect vblank signals) to separate back the 120hz stream into two 60hz streams, the former does not require any kind of special treatment. And this last one could probably be implemented inside gallium quite easily.
