In 5.2 and earlier, this happened routinely on some ports; for example,
NetBSD/sparc would start up using the OBP output and then, once the
console device (framebuffer or serial port, depending on the console
setting) got attached, would switch to using it.  I would assume it
still does, but I don't actually know; I haven't used post-5.2 on
anything but amd64.

Maybe looking at what they did would be useful?
