Framebuffer/vbe separation

Framebuffer/vbe separation

Hello, currently vbe module contains all the framebuffer functions which are
actually adapter-independent and I think more adapters can be implementing
by providing a function which sets mode and framebuffer. Additionally it
provides an interface to retrieve framebuffer address for loaders: check
that current mode is framebuffer based and if it is, take the address. May I
do it that way?

Yes. I have nothing against making frame buffer code as common code as
possible because other systems would also benefit from it. Just keep in
mind that other video drivers will also need to use it and do not call
directly VBE driver itself, provide proper interface over Video Subsystem.
