On the working kernel (6.99.28, sources dated 2013-12-09 01:36:15), I 
get what I would expect:

        raid0: RAID Level 1
        raid0: Components: /dev/wd0e /dev/wd1e
        raid0: Total Sectors: 488395008 (238474 MB)
        raid1: RAID Level 1
        raid1: Components: /dev/wd2e /dev/wd3e
        raid1: Total Sectors: 976770944 (476938 MB)
  >>>  boot device: raid0
  >>>  root on raid0a dumps on raid0b

Note that root is on raid0a and not on raid0e

Note also that there is another raidset, raid1.  It also autoconfigures, 
and everything is as desired.  Details for raid1:
