The file /etc/dhcp3/dhclient.conf is the file that controls resolv.conf (at least on this system). You can specify which DNS is used first by using
prepend domain-name-servers xxx.xxx.xxx.xxx; replacing of course the x's with the ip address of the DNS. This line is already present using 127.0.0.1 but is commented out. I have tried it, and it works.
