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 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*)

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