You would need mdadm-2.6 or later.  And that might get the checksum
wrong ... but it might be worth trying if you can figure a way to
do it.

What I would try would be:
  - --create the array
  - mount the filesystem
  - chroot /mount/point
  - mkinitramfs
(or whatever the command is).  Maybe it is "mkinitrd" in that
release of Debian.
Maybe Martin can help there?
