I had once given serious thought to what it would take to write an OS only
in a high-level language. (Standard ML was my language of choice at the
time.) The short answer is, no, it can't be done with Python as it currently
stands. 

First, you would need a Python compiler that can compile Python programs to 
machine code. Otherwise, what would you write your interpreter in? Python?
What would you write the interpreter's interpreter in? It can't be Python
all the way down. (Turtles are a different story, though. ;)

Second, in order to communicate with hardware, you would need modifications 
to the Python language so that you can read and write bytes to specific
memory locations. You would also need to be able to signal interrupts. Plus,
you would also need to be able get the exact memory location of functions,
in order register interrupt handlers.
