X doesn't allow any normal program to do page flipping*. In fact, the only
real way to get any acceleration in X is to use OpenGL**, and OpenGL doesn't
let you specify the use of page flipping.
* Though you could probably set a mode with a virtual screen size big enough
and scroll around, but you generally won't get a virtual screen size bigger
than the user's desktop size, and unless you're using a really low res mode,
won't have enough space for two pages.
** You could get some with DGA, but DGA isn't well supported anymore. They
recommend using OpenGL instead.
Mac is a different story though. Someone needs to write a proper
accelerated/OpenGL driver for that.
