First, run "lshal -m" and plug/unplug the devices to make sure HAL is
still sending out the hotplug signals.

If yes, then are the libhal integration functions in
src/NetworkManager.c:

nm_hal_device_removed()
nm_hal_device_added()

being called when the devices get hotplugged?

If not, maybe NM is getting kicked off the bus for some reason.  Try to
remove the:

	dbus_connection_set_exit_on_disconnect (connection, FALSE);

statement in the nm_dbus_init() function in src/NetworkManagerDbus.c.
NM will then exit when it gets kicked off the bus.
