As always, you are very right! And this is a very very very good idea, 
as it solves another problem we are facing:

(Martin, are you listening?)

Martin's special gpio-parport-soekris-whatever-it-is-called-today 
implementation that is capable of using 4 bits as input and 4 for output 
can be handled exactly this way!

So the user has to specify a "Model" in the config, if he specifies 
"gpio" (or however you want to call it, Martin), we suppose the user 
knows what he's doing, and allow 4-bit-busyflag. With all other models, 
we permit it.

Now that's what I call a clean solution!

bye, Michael
