    I think I've seen at least one system with a /usr/src/linux/include
    directory, but nothing else under /usr/src/linux. In that case,
    unpacking the tarball into /usr/src/linux directly could
    be...confusing.

    In the "include" directory of your configured kernel source tree. If
    you're building extra modules using kernel-package, this information
    will automatically be passed on (your source tree really can be
    anywhere). For building things that aren't available as Debian
    packages, you might need to go through an extra step to tell it where
    your kernel source is.

    (Alternatively, kernel-package can produce kernel-source and
    kernel-headers packages for you...but then you already have the source
    so this isn't the most useful thing. :-)
