You can spawn a login prompt on com0 through /etc/ttys and avoid changing
boot.conf. Enable tty00 in /etc/ttys.
That’s the best dual support you’ll get.
i'm afraid, this will not help me to fix filesystem errors, which i get
time to time because of power outage.
it's the main reason i wanted second console.

You can configure a serial console in boot.conf, and switch back to
the default local console by holding the Ctrl during bootup to skip
loading the conf file (on i386 & amd64 at least, not sure about other
arches). From boot(8):
boot.conf processing can be skipped, and the automatic boot
cancelled, by holding down either Control key as boot starts.
You've got to be very lucky with timing on some machines.
