Yeah, that's a known issue.  The problem is that the kernel does not
detect whether it has been booted from a serial console or not, and so
it will send output to the screen unless you give it a "console=ttyS0"
(or whichever serial port) argument on the kernel command line.

The goal is eventually to do this guessing either in the bootloader or
the kernel.  This is tricky to do in aboot because the CTB (console
terminal block) is seriously underspecified.  (I speculate that this
is because many (most?) implementations of SRM take input on the
serial port *and* the keyboard if both are present, though they only
sends output to one at a time).  It should be pretty easy to do in
MILO since MILO is actually a console rather than a bootloader :)

Hm, that's interesting.  So 2.0 would automatically detect a serial
console?  Or was there a separate boot disk for it?  (I seem to
remember that there was no "console on serial port" config option in
