There's a web page mentioning this board (note: entirely Japanese) --


The bottom part of the page states that Linux's lm_sensors 3.0.2 can
successfully monitor temperatures, voltages, and fan RPMs on that board,
very likely via SMBus.

Ideally I should be able to track down technical details by looking at
that code.  I'd feel much more comfortable asking Intel and having them
provide necessary registers and offsets, though; I prefer to avoid
reverse-engineering things if possible (less mistakes).
