The right thing to do is making Xorg stop using hal on !linux.

The hal init script will not be re-introduced.
If you want to see how hal handles (re)starting hald on upgrades, check the
postinst script, I basically does

get_pid() {
    [ -n "$1" ] || return 0

    dbus-send --system --dest=org.freedesktop.DBus --print-reply \
              /org/freedesktop/DBus
org.freedesktop.DBus.GetConnectionUnixProcessID \
              string:$1 2>/dev/null | awk '/uint32/ {print $2}'
}

# restart hald if it was running before
pid=$(get_pid org.freedesktop.Hal)
if [ -n "$pid" ]; then
   kill $pid 2>/dev/null || true
   lshal >/dev/null || true # will trigger through D-Bus activation
fi

The last step (triggering a hald start via D-Bus activation).
It was initially added for applications which used a buggy approach to check if
hald was running and disabled themselves otherwise, i.e. they didn't trigger a
D-Bus activation request.
All affected packages I know of have been fixed.
