I use kernel-package, and when I add or change a module I usually seem
to end up rebuilding everything anyway.  This is partly my
conservatism, and partly make-kpkg's conservatism; it and  its docs
tend to push complete remakes.  Also, if the new modules are in the
kernel tree, as opposed to the separate modules directory, I don't
know how to reach in and build just one part.

Can you give any pointers about how to get new or revised drivers in
with minimal building?

This is a special case of the general question "I just made a small
change to the kernel source; how can I avoid rebuilding everything?"
A lot of the answers have tended to "it's dangerous to try to do this,
just rebuild everything."
