It builds the full set of debian kernels. It unpacks the debian kernel
tree in a subdir, patches it with the mips-specific stuff, and creates
all the debian kenrel packages for mips/mipsel (depending on which
machine it runs).

This leaves you with a plain kernel unknown to the packaging system,
so you'll have to keep track of it manually instead of using dpkg.
With the debian source, you can do that as well, by calling
"fakeroot debian/rules patch" in the kernel-patch-2.4.26-mips-2.4.26
dir. This will create an already patched tree in the build-tmp subdir.
The debian kernel config files are in the /config subdir, copy it
over to <tree_root>/.config.
Now you can do:
make menuconfig
make dep vmlinux modules
make modules_install
Be aware that "fakeroot debian/rules clean" removes the whole tree, so
make sure to save your changes outside before you do that
(dpkg-buildpackage does that by default).

The idea is to allow automated builds of debian packages, with the same
dpkg-buildpackage working for _all_ debian packages. For a modified
kernel, you would create a patchfile for the modification and supply it
as a dpatch in the debian/patches directory (it must be executable and
added to 00list as well.). Once you did that, you can use the
dpkg-buildpackage command to create a complete set of kernel packages
with your modification. If you are only interested in the cobalt
kernel, comment out the other subarchitectures in the debian/rules
"subarches" spec.
