I was thinking something quick and dirty like so (note that this is 
thoroughly untested here in Powerbook land):

#!/usr/local/bin/bash
GATEWAYS="list of known default gateway IP addresses"
cp /etc/rc.conf /etc/rc.conf.start
cp /etc/resolv.conf /etc/resolv.conf.start
for GATEWAY in $GATEWAYS; do
	cp /etc/rc.conf /etc/rc.conf.last
	cp /etc/rc.conf.$GATEWAY /etc/rc.conf
	cp /etc/resolv.conf /etc/resolv.conf.last
	cp /etc/resolv.conf.$GATEWAY /etc/resolv.conf
	/etc/netstart
	if [ ping -oc1 google.com > /dev/null 2>&1 ]; then
		echo "Successfully configured network using \
			gateway $GATEWAY"
		exit 0
	fi
done
mv /etc/rc.conf.start /etc/rc.conf
mv /etc/resolv.conf.start /etc/resolv.conf
/etc/netstart
