Does the console have to be asigned to a serial or video driver ?

   
    I am working on a Linux Port to a very minimal Xilinx V4 FPGA card. 
At this point it would be extremely useful for me to assign the console 
to a fairly trivial char device that is little more than a 
bi-directional parallel port.

    Is that possible or do I have to impliment dummy code for all the 
required interfaces for a serial device ?
