If Penguin then loads the kernel in that same chunk, there really is no
other choice? (The kernel expects the memory chunk it runs from to be
listed first in the bootinfo struct).

I wonder about the 020 sorting scheme though - is there a hardware rule
that says the first chunk must be the largest on 020?
