Further investigation reveals more:

[root at adios init.d]# hal-device-manager
Traceback (most recent call last):
   File "/usr/bin/hal-device-manager", line 20, in <module>
     DeviceManager()

     "/org/freedesktop/Hal/Manager")

dbus.DBusException: org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.Hal was not provided by any .service files

Does this help in the location of the problem??
