IIRC, Vincent's suggestion is more valid for the HW guys who want to test
out all kinds of possibilities *before* the OS and the support for the drivers
becomes mature enough to concentrate on statistics and so on. Even I remember
our HW guys requesting for bersek controls over regulators and clocks as a part
of platform validation, when the OS was not mature enough in terms of a complete
system-support.
