Hi Robin,
I initially thought of using "IPMI - Broadcast Get Device ID" to
dynamically discover newly installed devices on the system. But even
Intel's ISM doesn't use this functionality. All SDR Repository records
are updated only through the firmware upgrade process provided by
Intel. 

Installing/Removing components like power-supply, fan, processor will
not affect the cache. SDR Repository already includes all possible
entries based on system's maximum capability. i.e. Even if the system
has just 1 or 2 PROCs installed , SDR Repository will have records for
all 4 processors.

Ignoring Un-installed Devices:
You may also find this option useful. For example, In a quad-processor
system, If you know for sure, you have only 2 processors installed,
You can safely choose to ignore those sensors like this, 

   ;; sensors-conf.scm
   (sensors-ignored-list "94 95")
