Are you talking about all 17 fields of the _PMC return value?  Or specifically
the feature bit field "Supported Capabilities"?  The feature bits control
whether or not the corresponding sysfs attributes even show up, and the other
fields (except the string data) are all there.  I suppose it would be useful to
display the OEM data too...
