I have added modules and compiled without "make-kpkg clean" a few times.
Only the new stuff is compiled in that case, and you do indeed save a
lot of time. However, I used the same revision number. I seem to
remember that compilation fails if the numbers do not match. It may be
possible to trick the kernel package by adjusting the revision number in
the appropriate log/status file, but I never tried that.

I think that there are cases in which module A tries to interact with
module B if both are present, and then there might be problems if you
just add one of them later without recompiling the other one. I have
only used this kind of "cheating" for very trivial cases, e.g. when I
forgot the pc-speaker module in the initial compile run.
