With this detection code getting increasingly more sophisticated, wouldn't
this be a good time to make it a video backend? (i.e. video/efi.c)
Even if it won't be complete enough for gfxterm yet, it's much better than
doing it in i386/efi/linux.c IMHO.
The code to obtain framebuffer address from video backends is pretty simple.
It's already in i386/linux.c and could be easily integrated into
i386/efi/linux.c.
