  I am OK with this, and it fits into the schemes.

  To some extent, the 'pm' part is also redundant, but was changed as
'freq' seemed too specific.  However, there is also some engineering
going into disabling cores, so there is the possibility that there
could be frequency control and core/chip disabling in the future.
However, it could also be argued that they both fit into the
system.power.cpu category.

  So again, I am OK with it being solaris.system.power.cpu, as this is
the current expected individual set, and if/when another set comes up
that requires something different, it can be revisited then.
