There is some minimal documentation available. Some Apple docs:

ADB-The Untold Story: Space Aliens Ate My Mouse
http://developer.apple.com/technotes/hw/hw_01.html

Inside Macintosh: Devices / Chapter 5 - ADB Manager
http://developer.apple.com/documentation/mac/Devices/Devices-203.html

These will tell you the basic design of ADB as well as the packet
formats and information about keyboards and mice.

Note that these document ADB in a generic sense, so nothing PMU
specific is in them. Apple has been very reluctant to document
the PMU and it's functions.
