Well the i830 page flip code is using async flips, the main thing I want
to use page flipping for on my i815 is sync'ed flips so I don't see the
tearing that is so really obvious and gives people headaches.. (don't
need to be getting sued here
correct, you can then work on
the page flipping as an optimization for full screen.

I think maybe I decided copying was ok as long as:
- you rig XAA (or whatever) to always draw into the current front buffer.
