The decision to add the functionality to vkbd or to split it out to another driver is a separate issue and I can make it later. I've been working on doing the mux as a keyboard driver the eats the other keyboards in the system. At this point I think that's the quickest route to a working system. Doing this as a separate function between the keyboard and the console makes some sense, but at this point I don't think it's worth the effort especially since we only have two consumers of keyboards (syscons and pcvt), both of which are bad examples to generalize from. -- Brooks --=20 Any statement of the form "X is the one, true Y" is FALSE.
