It won't.

Because that's the problem. SMI-based frequency switching is something
that takes a real long time (probably in the msec range), in which no
work can be done. So it is not useful to switch very often, and thus you
don't need a kernel-space solution.

Install powernowd, cpufreqd or something like that instead.
