some drives just return bogus temperature info -- I've seen that people
are working on it IIRC, but don't press me for details :-)

For instance though:
Jul 17 06:05:10 chupacabra smartd[784]: Device: /dev/hda, SMART Usage
Attribute: 194 Temperature_Celsius changed from 161 to 148 
Jul 17 06:35:29 chupacabra smartd[784]: Device: /dev/hda, SMART Usage
Attribute: 194 Temperature_Celsius changed from 148 to 157

This is a laptop drive sitting under maybe 1/2 inch of plastic, shock
absorption material, and my left hand. I'd know if it was really 322
degrees Fahrenheit.
