A mem= option in first32.c (mknbi) (from command line parameters or
option-129) similar to in LILO etc is probably a good idea.  first32.c
would note the value and use that instead of the BIOS value, then pass
it on to the kernel, as it currently does with all options not
recognised by it. I'm not sure how to specify the override, with another
option maybe?

In any case this will require reshuffling of the memory areas so that
first32.c can be larger than 4kB. I have already done this for 1.2.6 and
I'll CVS the source soon. Then if you feel up to hacking first32.c,
please go ahead, I may not get to it immediately.
