Take a look around Apple's site, particularly the developer section.
There's documentation in spades if you can read PDFs. Fact, that's
one of the best things about Apple - they document nearly everything
in public view.

Come to think of it, the kernel already supports a fair amount of
video hardware, through framebuffer. I don't know how capable that
is, though, beyond displaying and scrolling text in various
resolutions, and as a place for XFree86 to fall back to. If fbdev is
accelerated, some kind of userspace utility and kernel-space cleanup
would potentially allow fully-accelerated (including 3D?) graphics,
with much of the hard work in kernel space. Or is fbdev just a dumb
framebuffer and I'm totally off track?
