check to make sure you have :
/etc/init.d/networking
with these files linking to it:
/etc/rc0.d/S35networking
/etc/rc6.d/S35networking
/etc/rcS.d/S40networking

an update-rc networking defaults ,might solve this for you.

also, you might want to check out sysv-rc-conf, its a neat little app to 
configure your init scripts.
