Saying NetworkManager about active connection

[Boris Dolgov <nm-list dolgov name>]

Hello everybody!

To connect to the Internet I use device, which is not yet supported by
NetworkManager. But I like NetworkManager and use it to connect to
wireless/wired networks.

So, when I am connecting to the Internet, I have to kill
NetworkManager, connect to the Internet, change "Work offline" flag in
Firefox and restart applications, waiting for the network dbus
notifications (such as Pidgin).

How can I tell NetworkManager that the connection is already
established by another application? So, it will not generate empty
resolv.conf file, all applications will know, that there is the
Internet connections.
