We ought to write more documentation. :-)

The mini-OS doesn't currently do any I/O -- it's just an example of
setting up exception vectors, page tables, and other CPU stuff. This
is the kind of thing that tends to get buried in the bootstrap cruft
in a full-sized OS and so is useful to pull out into somethign
simpler. Device drivers are usually self-contained, and so easy to
find and understand -- hopefully the Linux virtual drivers will
suffice as a 'reference implementation'.
