I am working on rewriting an operating system that avoids this philosophy for the purpose of teaching assembly language. So far, I have 2% of the code (I started a rewrite), and I don't know if my code is 100% right.
There's an OS (complete with a Window Manager, IDE, Web Browser, and even some games) written entirely in assembly: http://www.menuetos.net/
