Okay, so the straightforward way to handle this is to load a libsa
based boot loader from the first "partition" on the floppy (or if
needed because you can't do partitioning on the floppy, from a first
floppy) and then read a tarfs. libsa already has a lot of the hooks to
do this -- you only need to write a polling floppy driver.
