FWIW, an overview of the NetBSD source tree is available here:

  * A Tour through the NetBSD Source Tree: Part I - Userland
    http://ezine.daemonnews.org/200203/netbsdsrctree1.html

  * A Tour through the NetBSD Source Tree: Part II - Libraries
    http://ezine.daemonnews.org/200204/netbsdsrctree2.html

  * A Tour through the NetBSD Source Tree - Part III: Kernel
    http://ezine.daemonnews.org/200205/netbsdsrctree3.html

A bit dated, but most things should still apply.
