Does "ps -ef |grep gdm" return anything?  That should tell if you it's
running already.

No, SELinux policy is only one small part of dbus security policy.

Right, in order to own the name org.gnome.DisplayManager there has to
be a file in

/etc/dbus-1/system.d

(by default called gdm.conf)

that has:

 <allow own="org.gnome.DisplayManager"/>

in it (among other things)

It could also be that gdm's idea of the system.d directory is
different than dbus daemon's idea.  (I have some vague notion of
someone on freebsd having to manually move files from /etc to
/usr/local/etc or vice-versa at some point)
