ISTR we disabled floppy support completely in debian in order to avoid this
kind of trouble (I would disable it in official GRUB as well, but I can
already feel there'd be some opposition :-)).

Anyway, my point is that floppies are too unreliable.  We detect them when
iterating even if they're not readable.  Perhaps we could actually probe them
for read during iteration to solve this.

This looks like a hack.
