I strongly second this. I've read the newbus page on freefall, the man
pages and the code and i still do not know where to start and how this
all fits together.

More, i think that core should make it mandatory for such dramatic changes
to the architecture, that this kind of changes are properly and completely
documented either before or at least within a fixed timeframe from the
time such changes are commited to the tree.

Don't get me wrong, it seems that the authors did a great job and i 
appreciate it very much!

Anyway, i don't think you are asking for too much - of what use is a shiny 
new design of a new subsystem in the very basic FreeBSD architecture if just
some handful few people knew how it works and how to use it ?
