Somewhere in my plan is a desire to add code to /boot (for i386) that
will read commands from a file before/instead of (etc) taking them from
the user. Also in the list is code to let /boot read a bootstrap from
a different disk.

This might do what you want without worrying about NVRAM layouts
and checksums.
