Installing Debian on modern hardware

Not really. I stopped building my own kernel packages for those two machines in question after Debian Stretch was released – meaning at that point Debian's kernel supported my hardware well enough so that I didn't need those custom packages anymore. In addition, the configuration was somewhat tailored to the specific hardware in order to keep the build time down.

What would probably be more useful than publish those outdated packages, are the scripts that I used to check for new releases and build/package them. But then again, if I were to publish them, I'd like to clean them up a bit first. There are a couple of things that I'd probably do differently nowadays. Just a brief example: Back then my scripts were still working with the release tarballs. Today, I'd probably just use git instead of downloading and extracting the whole source tree again for every release.
