The kernel ebuilds use an eclass (kernel-2) that handles most of that
patching for them, since they regularly have a large number of
well-defined patches.  Your best bet is to take one of the existing
patch tarballs (e.g. genpatches-2.6.32-1.extras.tar.bz2), unpack it,
add your patch to the end (the numeric ordering will be apparent),
then re-pack it with an incremented version number ("2") and note that
in the ebuild.  A more immediate result would be to create an EAPI=2
ebuild (which you should be doing anyway), add your patch to
${FILESDIR}, then add an explicit src_prepare to your ebuild like the
following:

src_prepare() {
    default_src_prepare  # do the eclass/ebuild default unpack/patch cycle
    epatch ${FILESDIR}/my_extra_patch-1.0.patch
}

I'd suggest cutting your teeth on a 'simpler' set of ebuilds before
trying to go all out and do a kernel one.
