I would first write a userland program to experiment with. Then I would move the code to the console driver thats because thats where the X server interfaces to the kernel to change the scan codes, etc.. so it is a natural place to put this sort of code in . Is just that for future reference with respect to the X server it is kind of nice to have all the code which requires kernel support to be in one module.
