OK, while I wrestle with having a proper method of detecting a missing 
vs broken fan, I've figured out why you're getting duplicate reports.

It seems that the ipmi device is actually providing two separate items 
to be monitored for each sensor!  It is monitoring the sensor's value 
being within specified limits, AND it is monitoring a general "critical" 
indicator.  Each of these is an independant monitor, and you're seeing 
each of them as separate events.  For what it's worth, I'm also seeing 
double on my acpitz sensors.

I don't think this happened previously, so I've obviously broken 
something.  I'll keep at it.
