Debian, and derivatives such as Ubuntu, declares a generic handler in
the halt script:
        # See if we need to cut the power.
        if [ "$INIT_HALT" = "POWEROFF" ] && [ -x /etc/init.d/ups-monitor ]
        then
                /etc/init.d/ups-monitor poweroff
        fi

This works for nut and apcupsd...
now, I've asked a long time ago to have libusb in /lib (instead of
/usr/lib) just to be sure that the lib is still reachable at shutdown
time (otherwise, the driver wouldn't ever fire up!)

the strange point is that we have validated it again this week (a new
MGE PSP release is underway) on Ubuntu (dapper and feisty), using nut
2.2.0 and it (the UPS shutoff / poweroff) worked! But I admit there
might be an upstart (the init replacement) specific out there...

Is the shutoff working otherwise (ie calling upsdrvctl -k (CAUTION: no
sensitive load on the UPS; only light bulbs or alike))?

A (temporary) workaround, if your unit provide a sufficient delay, is
to have the SHUTDOWNCMD in upsmon.conf pointing to a script calling
upsrw / upscmd to launch the delayed shutdown with enough time to
shutdown the system, and then call the shutdown / halt / whatever
command...
