My suggestion, and, I believe, the official Debian suggestion as well,
is to start using the make-kpkg utility (part of the kernel-package in
dselect). IMHO it makes the whole kernel building/module
building/kernel installation/module installation process a lot
easier. With it you produce a kernel*.deb file which, when you install
it, does everything you need, PLUS it runs lilo-config for you, PLUS
it sets up your system to run the necessary "depmod -a" for you on the
next reboot. Here's all it takes to get everything going:

cd /usr/src/linux
make <xconfig|menuconfig|config>
make-kpkg --revision mysys.1 kernel_image
make-kpkg --revision mysys.1 modules_image
cd /usr/src
dpkg -i kernel-image-2.0.3x_mysys.1_i386.deb
(I think it runs lilo-config here)
dpkg -i <whatever>-modules-2.0.3x+mysys.1_i386.deb
(Here it warns you that you need to reboot to get the module
dependencies right)


The second "make-kpkg" and "dpkg -i" are only necessary, *I believe*,
if you have some extra modules. In my case it was the PCMCIA
modules. The modules that are part of the kernel are in the
kernel-image*.deb file. But read the make-kpkg documentation to find
out what you really need to do.

Good Luck!
