I can confirm the behavior described above. Intrepid-5

ifup/ifdown uses the settings in /etc/dhcp3/dhclient.conf.
NetworkManager does not.

Workaround:
ln -s dhcp3/dhclient.conf /etc/dhclient-wlan0.conf
ln -s dhcp3/dhclient.conf /etc/dhclient-eth0.conf

Under "edit connections", <connection-name>, "IPv4 settings",
leave DHCP Client ID empty. Otherwise, it will send this string
as the DHCP Client Identifier, and it will not send a hostname.
