For the general idea, read 
http://2002.eurobsdcon.org/papers/ushakov.ps

For more details,

http://www.netbsd.org/Documentation/, there look especially at the
Device Driver Writing Guide and the Kernel Programming FAQ.

Most NetBSD kernel interfaces written in modern times have a man
page in chapter 9. You'll probably need to read pmap(9), bus_space(9)
and bus_dma(9) when porting to a new architecture, although often
(that is, with a same-cpu port) you'll be able to use an existing
port as a guideline, and maybe able to call shared code ...
