Hum... may I suggest you to disable the NetworkManager service at all? 
Not unistalling it but getting rid of it (avoid the service to be started 
on boot). If you are not using a laptop nor need a dynamic network 
management, it should be fine.

Also, do you have the "resolvconf" package installed? There are only two 
apps I'm aware of that can cause an empty "/etc/resolv.conf". One is NM 
and the other is "resolvconf". The third one should be a bug :-)
