Yep that is pretty much what it needs.  I cleaned up a lot more though
to make it work with other things too.

I just posted a patch to the mailing list that makes 180.29 build
perfectly with 2.6.29-2 and also works with linux-modules-nonfree-2.6,
which is something we have been trying to get going for a while now.

It doesn't involve any clever business with trying to guess if -common
is needed or not.  It just uses pure kbuild and nothing else and relies
on the headers to do the right thing.
