Hello,
Sorry for late reply, I was away from computer.

My starting point was indeed
http://www.lm-sensors.org/wiki/Configurations/Asus/M2N-SLI%20Deluxe

I added some names based on dissasembly of ACPI following instructions on this
page : http://www.lm-sensors.org/wiki/AsusFormulaHacking

And some other based on different messages on the lm_sensors list.

Hopes it will help someone.
