Asynchronous display controller? Attached via a serial link (or by other means), but no shared video RAM?

That's one of the more complicated drivers then... You'd need to prepare some buffer you can provide to the FB API and poll it for changes, which you then need to hammer down to your display controller.

So you need a shadow/bounce framebuffer if you *really* want to provide
it as a framebuffer; registering as a console might be simpler, but
won't provide graphic capabilities.
