So have you tried with 'ifnames=1'?

And are you sure, that the 'hwaddress' lines in your '/etc/network/interfaces' really define which NIC to use? AFAICT this option just changes ("spoofs") the MAC address of the NIC for which it is defined. Although the log confirms that finally eth0 is the tg3 NIC, this seems unusual (and very counterintuitive) to me.
