It works "normally" during the new-bus attach, but the low-level console code probably checks for it early on as well. The serial console code works that way. The uart(4) and sio(4) drivers explicitly look for uart/sio hints to find possible console devices. This is separate from when the ISA bus adds uart/sio devices from the hints later on. -- John Baldwin
