F9 Networkmanager and zeroconf

hi,

It seems that in F8, when nm failed to get a DHCP reply, it will use
zeroconf to get a IP address for NIC. It's something like this(fedora 8 log):

BUT, it seems that in F9, nm doesn't use zeroconf anymore. It just
failed when cannot get a DHCP rely.
This is very bad for me. I am using a pppoe connection. This new
behavior make the pppoe's NIC failed to
get a IP address and ppp dial will fail.
