Read man mksuncd:
http://www.openbsd.org/cgi-bin/man.cgi?query=mksuncd&apropos=0&sektion=0&manpath=OpenBSD+Current&arch=sparc64&format=html

I use a simple shellscript for this:

#!/bin/sh

# creates a bootable cd for sun ultrasparc

# Extra options for mkhybrid (-l -r is always set)
opts="-T -J"

# Name for the cd image
title="OpenBSD 4.5 sparc64"

# Preparer of the cd
prep="Maruweb"

# Publisher of the cd
pub="Theo de Raadt"

# File with bootimage
bimage="${1}"/4.5/sparc64/miniroot45.fs

# File in which the cd image should written
iso=install45.iso

# Check if the directory with the files for the cd, is
# given as an argument

if [ $# -ne 1 ]
then
   echo "This script needs an directory with files for a cd as an argument!" >&2
   exit 1
elif [ ! -d "${1}" ]
then
   echo "This script needs an directory with files for a cd as an argument!" >&2
   exit 2
fi

# Put slicemapfile in the root-directory of the cd

echo "m 1       sun4" > "${1}"/.slicemapfile
echo "m 2       sun4c" >> "${1}"/.slicemapfile
echo "m 3       sun4m" >> "${1}"/.slicemapfile
echo "m 4       sun4d" >> "${1}"/.slicemapfile
echo "m 5       sun4u" >> "${1}"/.slicemapfile
echo "m 5       sun4us" >> "${1}"/.slicemapfile
echo "m 6       sun4v" >> "${1}"/.slicemapfile

# Make the cd image

mkhybrid -l -r ${opts} -P "${pub}" -p "${prep}" -o "${iso}" "${1}"

# Make the image bootable (needs a already existing boot image)

vnconfig svnd0 "${iso}"
disklabel -w svnd0 fakecdrom
vnconfig -u svnd0
mksuncd f "${iso}" "${bimage}"
