NetworkManager automatically disables wired connection (rawhide 20071019 i686 live-cd)

[Arnout Lok]

hello,

I just tried the rawhide-20071019-i686 image. When I log in I'm
greeted with an NetworkManager-balloon saying:

Disconnected
The network connection has been disabled

(by the way, this balloon is loaded even before the panel and the
'point' on it is pointing to nowhere.)

a 'cat /var/log/messages|grep NetworkManger' shows the following:
Oct 21 21:30:39 localhost NetworkManager: <info>  starting...
Oct 21 21:30:39 localhost NetworkManager: <info>  eth0: Device is
fully-supported using driver 'atl1'.
Oct 21 21:30:39 localhost NetworkManager: <info>  Now managing wired
Ethernet (802.3) device 'eth0'.
Oct 21 21:30:39 localhost NetworkManager: <info>  Bringing up device eth0
Oct 21 21:30:39 localhost NetworkManager: <info>  Deactivating device eth0.
Oct 21 21:30:45 localhost NetworkManager: <info>  Trying to start the
supplicant...
Oct 21 21:30:45 localhost NetworkManager: <info>  (eth0) supplicant
interface is now in state 1 (from 0).
Oct 21 21:30:45 localhost NetworkManager: <info>  (eth0) supplicant
interface is now in state 2 (from 1).

There is no wireless or whatsoever on this desktop-pc. Why is
Networkmanager disabling my connection by default?

(I can enable the connection by clicking on the
NetworkManager-status-icon and checking the radio-group-button before
"Wired Network".)
