FREE=`free -m | grep Mem | awk '{print $4}'`
if [ $FREE -lt 256 ] ; then
echo "ONLY $FREE RAM LEFT ON $HN" | mail -s "RAM SHORTAGE ON $HN" you@you.com
fi

Should work fine if you run it from cron every 5 minutes or so.

Or you could try munin (http://munin-monitoring.org/) which is a great way to monitor resource usage. Setting up alerts in munin is a bit complicated though.
