I think this has been discussed previously, the conclusion being that kernel
modules should not diverge upon changes in the kernel configuration options. 

The practical case is: what happens when I try to load gpiosim(4) after
having compiled a kernel with a LUA option but not having updated
userland/modules (or vice versa)?
