No the Bach book would be useless.  I had always intended to write up a tech
report or something about the VM system for 4.4bsd (NetBSD is largely the
same) but I haven't gotten past the outline and introduction.  There will
be a chapter in the next edition of the BSD book, but that is a long way off

One place to start is:

%A A. Tevanian
%T Architecture-Independent Virtual Memory Management
	for Parallel and Distributed Environments: The Mach Approach
%I Department of Computer Science, Carnegie-Mellon University
%V CMU-CS-88-106
%D December 1987

Which describes the early Mach VM system from which the BSD system is
derived.  It will give you an overview of the basic data structures in the
machine independent and dependent levels.  I have never found an online
copy so you may have to order a paper copy.
