Better yet, patch your bootblocks to force a serial console.  The
bootblocks already allow you to toggle between the serial and graphics
console with -h; all you need is changing the default.  This gives you
the added feature that you can boot an alternate kernel even with a
serial console.

cd /sys/i386/boot/biosboot
vi Makefile		# remove a comment character there
make all install
disklabel -B sd0

That's all...

Never trust an operating system you don't have sources for. ;-)
