I use Tiny Core Linux in framebuffer mode every day. Ali G. Rudi's framebuffer tools were a huge inspiration: https://litcave.rudi.ir/

I've also been curious about fbui (in-kernel windowing system). Not sure how well it works with current kernels, though: https://github.com/8l/fbui

Having really modest needs, I even made an effort to use FreeDOS for essential tasks (writing, PDFs, some scripting), but gave up quickly as I cannot live without a good PDF pager or (for some tasks) soundcard support. I also had trouble with constant fan noise on DOS (you'll need some hacks to maybe get around this). It is still mind blowing how fast FreeDOS (or e.g. the even more barebones SvarDOS) boots. It took literally about 2 seconds to greet myself with the good old "C:\>".

Also, it is a system that fits inside the head of even an ordinary person. This is really refreshing these days.
