You have to create "SMALL" UFS partition for ofwboot.

See http://www.netbsd.org/guide/en/chap-rf.html.
I'm using NetBSD 2.0RC1 on ULTRA30. RAID-1 as /.  =

It seems that it is necessary to make it be the
same as NetBSD 1.6.x's example with sparc64 system.

My system's Disk label is
....
bytes/sector: 512
sectors/track: 509
tracks/cylinder: 4
sectors/cylinder: 2036
cylinders: 17457
total sectors: 35566480
.....
#        size    offset     fstype [fsize bsize cpg/sgs]
 a:  10505760      2036       RAID                     =

 b:   1050576  10507796       swap                     =

 c:  35566480         0     unused      0     0        =

 d:  24008108  11558372       RAID                     =

 e:      2036         0     4.2BSD   1024  8192   344  =

partition a: RAID-1 volume for /
partision d: RAID-1 volume for NFS export
and
partition e: UFS partition for ofwboot

[BOOT]
ok boot disk:e
or set NVRAM parameter
ok setenv boot-device disk:e disk1:e
ok reset
