Mine looks like this and works:

    #        size   offset     fstype   [fsize bsize cpg/sgs]
      a:  1572864     2111       RAID
      b:  4194304  1574975       RAID
      c: 120103137      63     unused        0     0         # (Cyl.    0*- 119149)
      d: 120103200       0     unused        0     0         # (Cyl.    0 - 119149)
      e: 114333921 5769279       RAID
      f:     2048       63     4.2BSD     1024   8192    32

You have to installboot the f partitions on both disks.
The kernel can reside on the raid partition because RAID autoconfig
will find it.

Hope this helps
