Mine is the same. I have:
set temp1_over 55
set temp1_hyst 50

Output is:
SYS Temp: +45.8�C   (limit = +50�C, hysteresis = +55�C) 

In this case, despite the labels, the alarm will go off at 55, and turn 
off at 50.

Although I'd still argue that if it were changed, people would find 
fault with the following scenario:

If the values are swapped, and limit is 50, hysteresis is 55....
Once the alarm is triggered, you could have output like:

SYS Temp: +52.8�C   (limit = +55�C, hysteresis = +50�C) ALARM

Don't get me wrong, I agree the output is confusing. Changing it to:
SYS Temp: +45.8�C   (alarm_off = +50�C, high_limit_alarm = +55�C)
would make more sense to me. :)

Different people have contributed code for various sensor chips. I 
wonder if perhaps some chips have the values reversed in the code, and 
others don't? I have a via686a chip.
