Hmm, as far as I see it there is no cleancut way to separate this into
multible drivers (or maybe I need someone explain it to me :-)
Either you have it like it is now, or you will have to have some
"interdriver" functionality to allow multiple drivers to muck with the
same hardware. A system to send messages between the drivers would also
be nessesary (ie user presses key to switch screen, a request for that
must be sent to the display driver, etc etc etc) Either way its a mess. 
The way it is now reflects the way the user see's devices (console, 
PCMaudio, mouse, whatever).
But anyhow, I'm open to suggestions as usual...
