Unfortunately I started celebrating too soon. The problem is still there.

I added a "cat /sys/class/net/eth0/carrier" in the init script, right before the
daemon is started. On startup I get a "invalid argument", then NM is started,
believes the link is up, activates eth0, eth0 gets and LL ip.
After I login, "cat /sys/class/net/eth0/carrier" yields 0, and nm-tool shows no
link.

The version is 0.6.5 with r2578 applied.
