Try the following line or a similar one in /etc/syslog.conf:

kern.* /dev/ttyS0

There are also some #defines in linux/drivers/char/console.c I never tried

if CONFIG_SERIAL_ECHO is defined, and
CONFIG_ECHO_PORT is set to the correct port (see comments), then the
system-console seems to be echoed to some serial line.
