We can look in /proc/ioports and see what has reserved

estimate of the video adapter.  We can do an ioctl to
the console and see how many lines and columns we have.

Reusing boot_params could be nice but if we have the information
available in other ways digging it out that way is quite possibly
better.

Another path:
LiuxBIOS+elfboot+payload, and payload is compressed elf
(vmlinux+initrd) via lzma.
and use kexec to boot final production kernel.
We don't need to use boot_params from the first tiny kernel.
