Either this or the sources of the Debian kernel that you are currently
running.  The latter may perhaps be preferable for an easier switch
between distributed kernel and patched kernel.

Alas not.
(I could build such a package if I had Debian myself, but I don't.)

OK; the patching as additional step is going to be the easiest one.

A quick web search turned up the following pointers for using a custom
kernel on Debian:
http://www.debian.org/doc/FAQ/ch-kernel.en.html
http://www.debian.org/releases/stable/i386/ch08s06.html.en
(I hope the described method provides an already configured kernel
source tree with Debian's configuration as baseline.)

Before you start compilation, save the email with the patch somewhere,
change into the top-level directory of the kernel sources, and apply the
patch with "patch -p1 < /the/path/to/the/email".
