well yes, the reason kernel images are not automatically upgraded from
r2 -> r3 is because its a different package

r2: kernel-image-2.2.18 Version: 2.2.18-1
r3: kernel-image-2.2.19 Version: 2.2.19-1

different package so why would apt upgrade it.  (and yes i know its
actually a pre-something in r2, thats beside the point).

if you create your own kernel-image-2.2.19 package and your version
number is not greater then the debian one then yes apt will try to
upgrade it like any other package, and this in fact occurs sometimes
in unstable dists since the kernel version is the same, but a few
debian revisions will be done (-2 -3 -4 etc), this very rarly to never
effects the stable release since by the time a new stable is released
a much newer kernel is available and used.

its also possible the 2.2.19 images will get a backported security
patch which would cause an automatic apt upgrade for anyone with the
2.2.19 image already installed.

as for your custom kernel problem the solution is trivial:

make-kpkg --revision=5:2.2.19-1

or --revision=5:2.2.19-`hostname`.1  is something i use.  the 5: is an
epoch which will make your version number always newwer then any
debian version (unless a debian kernel somehow gets an epoch larger
then 5, a very unlikly scenerio).

one last point, if you never actually install a kernel-image package
after you install a new system from boot-floppies apt will never
upgrade you kernel, since boot-floppies don't install any kernel-image
they simply untar the modules into /lib/modules and cp the vmlinux
files to /boot and symlink it to /  dpkg never knows about it.
