After a few email exchanges with you NetBSD guys, I realized 
LatticeMico32 MMU was missing a very crucial part: a documentation :)

So here it is now: [0]
You can download the PDF from this link if for some reason it fails to 
build from the LaTeX file: [1]

[0] -- 
https://github.com/milkymist/lm32/commit/4c0f6c51253b4482fe7685e77d4d5549207a098c
[1] -- https://docs.google.com/file/d/0B1EmiqYDjoD1VV9PbE5Pa1FUTms/edit

I hope this documentation will set clear how the lm32 MMU actually works 
and therefore how it can be used in order to run NetBSD kernel and 
userland by using its - basic - functionalities.

Don't hesitate to tell me if something is unclear or seems wrong or 
whatever!

Cheers,
