I tested a system with with softraid only for /home, run into the
problem and solved this with auto=yes also.
There IS definitly a change in the new kernel which prevents the creating
of the /dev/md? files.

This ist really a showstopper for all systems  with softraid
upgrading to 21mdk, because auto=yes ist NOT the default during a 2006
installation!

I think you should make an announce of this Bug on the sec announce
list, to help other people not to run into the same problem.
