No, but I don't think it would be difficult to add a way than just
choosing the first one. However, I'm not sure how to choose an
interface generally. If an interface is a PCI device, you may choose
it by a bus number, an I/O address, etc. But if it is an ISA device,
that's impossible (in part because of the implementation of
Etherboot).

Another way is to have GRUB to list all avaliable interfaces and
choose one of them. This requires that you rewrite the initialization
code somewhat, but this is still straightforward.

Of course! :)
