I've updated the sun-lamp sources to the point that they should work
with NetBSD-current--for the most part.  If you get the entire -current
kernel distribution from sun-lamp (minus, perhaps, the other arch
directories), do the following (and let me know if it works ;-):

	cd ~src/sys
	mv scsi scsi.dist
	ln -s arch/mac/scsi scsi
	cp mtio.h sys		# Where mtio is the one that follows
	cd arch/mac/conf
	config.new GENERIC	# If this wasn't in the dist, please let
				# me know...
	cd ../compile/GENERIC
	# Make sure that your compiler defines at least the following:
	  __BSD_NET2__ mac macII __NetBSD__ mc68000 __mc68000__
	  mc68020 __mc68020__
	# If not, then add them to the list of defines in the Makefile.
	setenv ARCH m68k
	make depend
	make

Hmm.  It occurs to me that you'll want some files from libc/arch/m68k,
as well:
	lib/libc/arch/m68k/DEFS.h
	lib/libc/arch/m68k/string/*
	lib/libc/arch/m68k/net/*

Cheers,
