If you want geographical type device specification hierarchies, to sanely manage that kind of stuff, they belong via sysfs or something userside like that. Using a bunch of different majors does not help the situation you speak of. What if I have 1,000 cyclades cards in my system? The cyclades serial major number helps me diddly in that case. What about having 82 8250's?
