Can you steal code from LILO to patch the in-core kernel image with
values it needs?

Right now the Linux kernel depends on a memory map read from BIOS.  One
solution -- which I think should belong in the official kernel -- might
be to create our own memory map, and then pass the physical address of
that map into the kernel image.
