As for the main topic, I'm just going to wait until Soekris gets back to me with
some more info before asking for more of your time. :)

Yep, they do work great for us in the majority of cases.

Ah, ok, I didn't realize this.

Well, now I'm really straying from the topic, but I don't seem to have much luck
with getting alarms to triger consistently using the asb100 chip on an A7M266
board. It uses set temp_over and temp_hyst rather than min and max. AFAIK,
silly Asus continues to refuse to supply a datasheet for this chip. I believe
the Alarm Notes section describes some of these problems:
