This hasn't been working for a while, not sure why.  NetworkManager
seems to run fine.

I have dbus running:

[clarkbw@rhbw ~]$ ps ax | grep dbus
 2748 ?        Ss     0:00 dbus-daemon-1 --system
 3690 ?        Ss     0:00 /usr/bin/ssh-agent /usr/bin/dbus-launch
/etc/X11/xinit/Xclients
 3694 ?        Ss     0:00 dbus-daemon-1 --fork --print-pid 8
--print-address 6 --session
 4419 pts/2    R+     0:00 grep dbus

Here's the relevant debug info:
