The setup here is:  the ROM is set to always direct the console to the
serial port.  So, bootup will always go to the serial port.

If the machine is to run unattended, I think it is paramount to unplug the
keyboard in this circumstance, as it would not always be possible to perform
a keypress when rebooting.  A simple accidental keystroke on the keyboard
once booted was all it took to trigger the panic.  I'm of the opinion that
this is probably something that should be rectified--finding a way to have 
the kernel recognise the keyboard when it isn't the console and handling 
the interrupt or whatever hardware issue is at fault.  

Thanks :)
