Linux has a LED subsystem for that. May I suggest, that you just register
these leds and let userspace handle them via that via the LED API?

The LED userspace API is described in Documentation/leds-class.txt
and the headers for registering LEDs is linux/leds.h under include/

Since you explicitly WANT user space to control these, that should
be the right API. 

Richard, what do YOU think?
