If you think it fits reasonably into the virtio spec (ie doesn't
implement things at the wrong level of the transport/backend
abstraction) then we can implement it in QEMU, and I think it
makes more sense to do this than to throw in a random extra
serial port.

To be actually useful we need to also specify something in
the device tree to say "here is where you will find your
emergency output and what it is".
