It's a good idea. VT switching isn't hard to track reliably.
Being able to tell qemu, through the monitor, to attach/detach from a
particular VT might be a nice easy bonus too.

I'm not sure if DirectFB provides that particular operation, but I
have the impression it's the sort of thing DirectFB is intended for: A
framebuffer, plus a variety of 2d acceleration methods (and other
things like multi-buffering, video and alpha channel overlay).
