Kelmo, I think I "kinda" understnad...

Say I did the:
apt-get install alsa-source nvidia-kernel-source i2c-source
cd /usr/src/linux
make-kpkg modules_image

... but I already have the nvidia-kernel-source from the "initial guide" here, so that can be removed from the apt-get install

I would add those .deb packages that I created above, in the steps - looking at the "initial" posting here to get NVidia into the kernel, either just before, or just after the following step:

...
dpkg -i nvidia-kernel-2.6.6_1.0.5336-6_i386.deb
...

and then continue with the rest of the "initial" Guide here...

Right? ( am I getting it now? Is a large 500 watt light bulb going on over my head? )
