I don't see the problem. If there is a lower priority console available
then the kernel can use that anyway and clearly that would be the right
thing to do.

The case that wouldn't work perhaps is the 'no console present and a USB
or firewire one might appear' - for that to work you'd need the queue to
be smarter - or even the lowest priority console...
