You could read different parts of the floppy for different keys.
Speaking of which, do the keys have any identifiable strings in them? If
not, you could fill the floppy with random garbage and 'hide' the key.
I'm assuming since you don't want a password you don't want the boot to
require interaction so it's not that useful, but if nothing else it would
help if someone got access to the floppy (remotely or by physical access).
