Answer later. We are always free to roll our own. For most folks,
it's really only necessary to boot the OS. After that, the OS
takes over. For graphics modes, a custom guest-specific video driver is best.

I have some idea on the architecture of passing data between the
guest and host OSes. I'm hoping some others render some opinions
beyond that because I'm not much familiar with direct video
facilities. Let me know if you want ideas with general
architecture.
This kind of thing will be important to performance for plex86,
so it's good to start looking into it. And we're getting
close to the point where we can start using special drivers.
Here's some notes I have:
