Stefan, could you please show us the contents of /etc/NetworkManager/NetworkManager.conf? In the early stages of systemd's integration in Gentoo, it was necessary to disable some plugins that tried to set /etc/conf.d/network as configuration file for NetworkManager. I don't know if it's related to your system connections not appearing in /etc/NetworkManager/system-connections.
may I tell you a secret? The laptops run fedora :-P if you still listen: the NetworkManager.conf contains only commented lines.
