i had to apply this simple patch to the /etc/network/if-pre-up.d/ifenslave
script for ifenslave.

https://bugs.launchpad.net/ubuntu/lucid/+source/ifenslave-2.6/+bug/482419/comments/28

and my interfaces file looks like this:

iface eth0 inet static
iface eth1 inet static
iface eth2 inet static
iface eth3 inet static

auto bond0
iface bond0 inet static
        hwaddress ether 84:2B:2B:07:08:9C
        address 10.0.0.11
        netmask 255.255.255.0
        slaves eth0 eth1 eth2 eth3
        bond-mode 4
        bond-miimon 100
