No, this has nothing to do with mdadm.

But it should not behave like this, and in my experience it doesn't.

There was a bug related to this that was fixed in 2.6.25, but I'm
fairly sure lenny has a more recent kernel than that (??).

How exactly did you reboot?  Just "shutdown now" or "/sbin/reboot" or
"turn power off" or ...

Exactly what kernel is used during the install?
