Is there a PS/2 keyboard hooked up to this machine when you're
attempting to get serial console output?  If so, I'm not too surprised
it doesn't work (re: -P flag).

Can you try the following?

1) Removing kernel_options and console from loader.conf
2) Place "-P" in /boot.config instead

If this doesn't change the behaviour, please replace -P and with -D -h
and see if there's any improvement.
