Unfortunately, I'm not sure how to get my current superblock version:
$ sudo mdadm --examine /dev/md2
mdadm: No md superblock detected on /dev/md2.

use --detail instead:

c2stable ~ # mdadm --detail /dev/md126 | grep Version
        Version : 0.90
c2stable ~ #

HTH,
Mark

Yup. 0.90
$ sudo mdadm --detail /dev/md2
/dev/md2:
        Version : 0.90
  Creation Time : Tue Oct 27 09:45:39 2009

Wow.  It's younger than I thought.

Thanks!
