Please do it in generic code.  You may only need it on ppc today, but
somebody else is going to want the same thing tomorrow on another arch.

It's also nice to keep all of the stuff doing the actual sysfs munging
in one place.  I know it'll cost a few stubs for calling in and out of
arch code, but it should save some work down the road for somebody else.
