Your serial console is /dev/ttyS0, or something similar.
the tty command will tell you which tty you are on.
So now you can add a few lines to /etc/rc.d/rc.S (or whatever your linux
  flavour uses to initialise single user before going multi)

If `tty` returns ttyS0 then cp /etc/inintab.serial /etc/inittab
  else cp /etc/inittab.kbd /etc/inittab

Exact implementation is left as an exercise for the reader
IOW it is 0dark30 and I am tired.
