The consensus is as follows:

   1)  Typing "setenv console s" at the boot monitor forces the
system to use a serial console, even if a frame buffer/keyboard/mouse
is present.  "setenv console *" un-does this.

   2)  Disconnecting the keyboard should also make it use a serial
console; it is not necessary to remove the frame buffer for this
to work.
