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.
