Hi!
This may not be what You want to hear but there are so many stripped down OS-distributions already. Maybe it's part of Your work but I personally wouldn't go through re-inventing the wheel for every hardware that You will need support for. Unless that IS Your goal with Your studies.

FreeDOS, Linux, or BSD based. The have most of what You need for hardware support and fit on anything from a floppy to a credit card sized CD. And on lots hardware architectures. The first thing I would do is to take any of those, maybe even a normal distro, auto login a user (from inittab or tty1.conf) and start the desired application. No window managers or other fluff. Maybe You don't need a GUI? Even easier. Determine what You can remove in terms of services and unused programs. Most drivers are modularised. But all that is with regard to disc space, if it ain't running, it won't consume any RAM or CPU.

And please be aware that there is a big difference between what comes with the OS and the user environment, that's usually what makes the distributions unique. The OS (kernel and drivers) doesn't contain very much "user friendly mess". And that is a good thing!

Best regards,
Lakris
