Thats more complex than it needs to be. Easy solution is to allways compile in full set from semiconductor vendor and then maybe only use subset. 'Changing kernel is hard, lets do it from initscripts' is perverse reason for overdesign... (And btw it should be kernel doing the hardware abstraction, you are turning things upside down).
