That's what I originally implemented.  The problem is the negotiation can take
an unbounded amount of time to execute, so if it's run from the command line
then it needs to be interruptible (EG: with Ctrl-C), which means it needs to
be able to return an error.

I can see if I can come up with yet another possible alternative, but I'd like
to try to get the less-controversial patches (especially the GPIO header and
the e1000 ones) merged first.

Cheers,
