Just FYI, "hints" aren't. Er, acpi ignores them. We found that if
ACPI wants 2F8 on a given sio port, it was better ... er, only
worked ;-) if we configured device.hints to match what ACPI expected.
FYI, you might find "-dH" in /boot.config to be more useful that the
console setting in loader.conf. It sets console=comconsole by
default, but leaves you able to override it from the vid console if
you are at the keyboard when it boots. Very useful.
