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... -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Soren Schmidt (sos@FreeBSD.org | sos@kmd-ac.dk) FreeBSD Core Team ..
