a. why are all of these drivers "bool" (y/n) instead of tristate (y/m/n)?
i.e., why are they not buildable as loadable modules?

b. The .c and .h files have lots of comments in them that begin with "/**",
which in kernel-land means kernel-doc notation... but they are not in kernel-doc
notation. Please see Documentation/kernel-doc-nano-HOWTO.txt for info on how
to use kernel-doc notation.
