NM does not modify /e/n/i. That is one of my main complaints about it...

Do you have "auto" lines for your nics?

my /e/n/i:

***start***

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp

auto wlan0
iface wlan0 inet dhcp
wpa-ssid xxx
wpa-psk xxx

***end***

(I assume that /etc/init/networking.conf is present and unmodified to
run "ifup -a" at boot)
