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.
