Compression and encryption of the suspend image can probably benefit from
higher CPU speed.

We probably should do a survey on how many distro kernels have "performance"
compiled in statically vs. as a module, i know we have:
Because the userspace governor might not be loaded at all, so we'd have
to check this.
OTOH that's the job of the distro packager to make sure that the pm-utils
settings matches his environment, so i do not care too much.
