Okay, here is my attempt at starting Chapter 6 for MILO, attached as a diff against
the HTML version.  (What's the original in, HTML, LaTeX?)  Please critique and add,
but can't promise I'll finish it anytime soon though...  I've never used SRM, is that
what the current docs describe, or is what's there just ripped from the Intel docs
with no relation to Alpha whatsoever?  I've assumed SRM in this diff.

Anyway, a start for people to chew on. :-)
