HAL 0.5.8 initializes the D-Bus connection _after_ it has dropped privileges,
which means that D-Bus sees the HAL bus connection as UID 68 (haldaemon).  Thus
the NM policy prevents HAL from sending signals to NetworkManager.  Later
versions of HAL initialize the D-Bus connection before dropping privileges
and thus do not have this problem.
