Thanks John. This came *very* close to working :)

  monster:/dev# mknod fd0SSDD b 2 12
  monster:/dev# dd if=/dev/fd0SSDD of=~/beesystem.bin
  720+0 records in
  720+0 records out

Unfortunately, it writes a disk that my 'Bee doesn't recognise as a boot
disk. http://www.tux.org/pub/tux/knaff/fdutils/disk-id.html suggests
grabbing fdutils and issuing a command along the lines of `setfdprm
/dev/fd0SSDD sect=40 hd ssize=128 cyl=80` (with correct settings though;
that was just a pasted example).

Looks like this might just be a doable proposition :).
