Your a) and b) are in logical conflict. If they are only simple integers 
(in general sensor can be more complicated than single integer) why 
userland driver is ever needed? Simple daemon is enough.

I think loadable kernel modules are not worse than userland drivers since 
can be used only by those who needs them.
