Just checked the rules on my system, currently on debian the hal udev rules are
run before the hotplug compatibility rules. Could try to rename
050_hal-plugdev.rules in /etc/udev/rules.d to say z99_hal.rules and see if that
helps ?

Also please try to leave the nut user out of the hal group, i don't think it's
necessary...
