Well, for ports that use MI SCSI, finding the SCSI disk devices should be 

md_get_diskdevs() {
	# return available disk devices
	grep "^sd.*bus.*:*cyl," /kern/msgbuf | awk '{print $1}' | sort -u

md_get_cddevs() {
	# return available cdrom devices
	grep "^cd.*bus" /kern/msgbuf | awk '{print $1}' | sort -u

md_get_ifdefs() {
	# return available network interfaces
	for _netifname in ed el eg ep ie le; do
		grep "^${netifname}.* " | awk '{print $1}' | sort -u

This is similar to the approach Paul and I took with the hp300/sparc (and 
sun3, too)  Eventually, most (all?) ports might be able to 
use this script after .'ing in a machine-dependent module that defines 
certain functions.
