I don't believe that mmap support will help. The Xv code is pretty efficient and if mmap were there I am not convinced it would help. The extra data that is required to be transferred for these cases over that needed for Xv hurts the system a lot. I agree if you are just using X then fbdev etc. may be more efficient. There is still more work to be done to improve the Xv driver a bit more so that may well help.
