So make this a small RAM disk ... actually, you'll end up with something
comparably big if using "normal" programs, because of libc and general
bloat. But if you merge all the functionality into one single executable,
you should be able to get away with something like 100 kB.

It can't. The FIBMAP ioctl can only return the offset on a given device,
not the effective device, which isn't sufficient for md. Extending LILO
to handle files that are scattered over multiple devices would be a bit
messy, but doable.
