I think this is for some systems with buggy firmware?
For other systems with different buggy firmware you
should leave the "video" keyboard connected, at least
if you need to get into the firmware's "setup" mode.

What you need to do will vary with your system and what
capabilities/bugs it has.
For my system,
firmware:
advanced cmos setup page:
turn on serial console
turn on "keep running after boot" option
set baud rate
FreeBSD 6.0:
rcsdiff -r1.1 /etc/ttys
===================================================================
RCS file: /etc/RCS/ttys,v
retrieving revision 1.1
diff -r1.1 /etc/ttys

cat /boot/loader.conf
# -- sysinstall generated deltas -- #
console="comconsole"
# 0 = disk write cache off safe
# 1 = disk write cache on fast
hw.ata.wc=0
Bugs:
I think some of the bootloader stuff is hard coded to 9600 baud?
The FreeBSD boot loader has a menu thingy that doesn't listen
to either keyboard.
