Ah, well, you're making progress. The analog_out was intended for controlling fans, so I wouldn't be surprised if you can tie an alarm or something to the analog_out? Take a peek at the datasheet for the most accurate and detailed info: http://www.national.com/pf/LM/LM87.html#Datasheet It's possible that the initialization function in the LM87 driver in lm-sensors is overriding the settings that the Bios does.
