OK. Done

yeah.  /etc/init.d/lm-sensors reads

    #!/bin/sh

    . /lib/lsb/init-functions

    [ -f /etc/default/rcS ] && . /etc/default/rcS
    PATH=/bin:/usr/bin:/sbin:/usr/sbin
    PROGRAM=/usr/bin/sensors

    test -x $PROGRAM || exit 0

    case "$1" in
      start)
        log_begin_msg "Setting sensors limits..."
            if [ "$VERBOSE" = "no" ]; then
                /usr/bin/sensors -s > /dev/null 2>&1
                /usr/bin/sensors > /dev/null 2>&1
            else
                    /usr/bin/sensors -s
                    /usr/bin/sensors > /dev/null
            fi
        log_end_msg $?
        ;;
      stop)
        ;;
      force-reload|restart)
        $0 stop
        $0 start
        ;;
      *)
        echo "Usage: /etc/init.d/sensors {start|stop|restart|force-reload}"
        exit 1
    esac

    exit 0

The only other thing that I know I am interested in is displaying more
S.M.A.R.T. monitor info, which I think is a ksensors issue rather than
an lm_sensors issue.  That said, what other sorts of information is
available?
