Most likely it is not ifup, but some DHCP client that is being
started. When debian boots, it runs 'ifup -a' (see
/etc/init.d/networking) to bring up things listed as auto. If you
think ifup is at fault, why don't you try 'ifdown' on all your
interfaces, and then 'ifup -a' to see what it does?

There is no such relationship AFAIK that is set up by default. You
certainly should not have to modify /etc/modules as you suggest.
I suggest you modify your interfaces file so that eth0 is given a
static address with no auto keyword. If you still get a dhcp address
then you can be sure that it is not ifup that is at fault.
