simple dbus & python query.

[John (J5) Palmieri]

You are using the 0.2x API.  The newer API looks like this:

bus = dbus.SystemBus()
hal_manager_obj = self.bus.get_object("org.freedesktop.Hal",
                                                               
"/org/freedesktop/Hal/Manager")
hal_manager_iface = dbus.Interface(self.hal_manager_obj,
                                                           
"org.freedesktop.Hal.Manager")
