As far as I can determine, "-device e1000,netdev=0" doesn't go through net_init_nic() and doesn't put an entry in the nd_table[] for the NIC. This means it's broken, because a lot of board models look in nd_table[] to determine whether the user requested a NIC and whether it's the right type. So I think that in some ways this is just showing up an existing problem with trying to instantiate a network card with -device. -- PMM
