This is a strategy that should work. Attached is what I think is a
suitable Makefile for the temp directory. It's basically a combined
version of the Makefile in the release notes plus the Makefiles in the
three module directories.

You'll probably want to run "strip -g *.ko" after building the modules,
before installing them to somewhere under /lib/modules/`uname -
r`/kernel/drivers and running "depmod -a"

Good luck!
