I tried applying the patches on todays current (amd64) but there have 
been a lot of changes in this driver lately so I had to apply one hunk 
by hand.

With a BCM5704 chip (Supermicro H8SSL-i) the box hangs solid after 
setting hostname.

With a BCM5721 chip (Supermicro P8SCi) i get "RX CPU Self diagnosis 
failed" and no ethernet interfaces at all.

Do you have an updated/working patch set?
