 When you query a poweredge r610 with IPMI, it reports 7 sensors
 named 'Temp', all are in the state 'Disabled' and ipmitool says that
 no readout is available (but some thresholds are).
 
 The only temperature sensor reporting something is one of the three
 'Ambient Temp' sensors.

 Entities 3.1/3.2 are the CPUs
 Entities 10.1/10.2 are the Riser cards
 Entity 7.1 is the system board
 Entity 8.1 is unspecified
 
 
 So it looks like our driver doesn't ignore the disabled state correctly.
