That should work. The guy who wrote the serial console kernel stuff,
also wrote sysvinit, and also happens to maintain the Debian sysvinit
package :)

Did you:
a) create a new /dev/console
crw-rw-rw- 1 root root 5, 1 Apr 24 10:22 /dev/console
b) run a getty on /dev/ttyS0 (or S1, or whatever)
S1:23:respawn:/sbin/getty -L 9600 ttyS1
?

That's not possible. The kernel messages can go to either or both,
but init and the rest of the userlevel programs open /dev/console which
only outputs to one console (serial or VGA), not 2.
