I would of course like to be able to > use mdadm for this job :-) This would be one of the reasons that I neither use nor recommend RAID autostart. It is too dependant on the preferred-minor which is hard to change. I guess I could add an option to mdadm to change the preferred-minor as it could be useful, but I'm not highly motivated. Maybe a --rewrite-superblock option to --assemble... I recommend that you enumerate the uuids of your arrays, create /etc/mdadm.conf to say which uuid matches which /dev/md? and use mdadm --assemble --scan to assemble your arrays.
