I must be doing something wrong.  Tried the same trick again tonight using 
-current on a different disk - and here's what happened.  Any suggestions ??
--
# uname -a
NetBSD perentie.myplace.com.au 1.6ZG NetBSD 1.6ZG (GENERIC) #0
# cat /etc/raid0.conf
START array

START disks
/dev/wd1a
/dev/wd9a
START layout

START queue
fifo 100

# /sbin/disklabel  /dev/wd1
  ..
16 partitions:
#        size    offset     fstype [fsize bsize cpg/sgs]
  a:   4144707        63       RAID         # (Cyl.      0*-   4111*)
  c:   4144707        63     unused  0 0    # (Cyl.      0*-   4111*)
  d:  20005650         0     unused  0 0    # (Cyl.      0 -  19846*)
  e:   4144707        63     unused  0 0    # (Cyl.      0*-   4111*)
  g:    208845   4144770     unused  0 0    # (Cyl.   4111*-   4319*)
  h:  15647310   4353615     unused  0 0    # (Cyl.   4319*-  19842*)

# raidctl -C -v /etc/raid0.conf raid0
raidctl: invalid device: /etc/raid0.conf
