I run with the following in my /etc/rc.local -- I don't remember who
posted it, but I picked it up from this list some time back:

if [ -f /var/log/dmesglog ]; then
	echo -n 'checking hardware config:'
	mv -f /var/log/dmesglog.3 /var/log/dmesglog.4
	mv -f /var/log/dmesglog.2 /var/log/dmesglog.3
	mv -f /var/log/dmesglog.1 /var/log/dmesglog.2
	mv -f /var/log/dmesglog.0 /var/log/dmesglog.1
	mv -f /var/log/dmesglog /var/log/dmesglog.0
	dmesg | tail -r | sed /^NetBSD/q | tail -r > /var/log/dmesglog
	rm -f /tmp/diff.$$
	diff -bc /var/log/dmesglog.0 /var/log/dmesglog > /tmp/diff.$$ 
	if [ -s /tmp/diff.$$ ]; then
		cat /tmp/diff.$$ | Mail -s "Hardware change detected" root
		echo ' changed.'
	else
		echo ' no change.'
	fi
	rm -f /tmp/diff.$$
fi
