The STR implementation for powerbooks predates the generic STR support
(by quite a long way, it was originally done in 1998).  These days it
uses some parts of the generic STR support but the top-level control
is still using the old code, because the generic STR code doesn't
provide all the hooks we need yet.

For historical reasons, the top-level powerbook STR code is in
drivers/macintosh/via-pmu.c, and is invoked via an ioctl on /dev/pmu.
