A quick web search yielded:
http://www.linuxhq.com/patch/20-p0100.html
ftp://ftp.cistron.nl/pub/os/linux/kernel/v2.0/unoff-patches/
The latter probably is the "canonic" site since this is the domain the
author (Mike van Smoerenburg(sp?)) is mailing from.

The kernel command line parameter is for box B. It tells box B to redirect
console output to its serial port. You would then start a terminal program
like minicom or Seyon on box A that listens on box A's serial port that is
connected with a null-modem to box B's serial port.
Does that make things clearer to you? Or have I made it worse? :)
