linuxrc uses the /linuxrc.tty device. Change the properties of this device
to get the linuxrc output to go where you want. You can play with the
kernel parameters to get the kernel to spit out startup info on specific (or
multiple) terminals.
You can perhaps replicate the output of linuxrc using the tee command or
creative use of redirects in linuxrc, but I'm not sure how you'd join the
keyboard and serial inputs...
