well, as of now one question. I am planning like this :

                       sys
         _______________|_____________
         |	|	|       |    | 
        bus
________|______
              |
           parport
       _______|_____
       |            |
    devices       drivers- lp, ppdev, panel etc.. 
  _____|________
  |            |
parport0      parport1


I can understand that drivers need to be binded to one device, so
suppose ppdev wants to use parport0, how that binding will be done?
do i need mark the driver in the parport->ddev.driver ?
I think that should have been automatically done if i have a probe
function for the bus...
somehow I am missing this step in the other drivers codes.
