The RandR extension permits this, and I'm working on the XFree86 RandR support to provide for hardware supported rotation. I've hacked in software rotation support, but that isn't going into XFree86 anytime soon as there are conflicts with XAA, Xv and GLX. Hardware support is significantly easier. The only requirement will be to allocate a square frame buffer area so that rotation doesn't affect the 2D pixmap allocator used by the current acceleration architecture. When I receive hardware (promised, but not delivered), I'll get this running. Alternatively, if you've got a board to loan me in the next week or so, I'd use that instead.
