It could use some sort of re-org I suppose.  But not in 2.4 :)

I'm not sure. :)  It's a 6 question menu, keep in mind... (With 1 that
actually depends on something else, code-wise.  Which is why if we
really want to try and clean up the logic and compile issues,
drivers/input/Config.in should probably die... (Or never be called
directly on arches which do get drivers/char/Config.in)  And some of the
joystick stuff re-arranged..

heh.

Hopefully with 2.6 the input stuff won't suck as much.
