The claim that "That cpufreq driver fails gracefully on other (non IBM, OPAL) powerpc platforms that don't have the expected files in the device-tree" seems to imply it should be perfectly harmless on pre- power8 platforms. Of course, I'll put it through its paces on a couple such machines to make sure anyway. :P

It is not automatically loaded in the boot process (even when included in the initrd). It is desirable to have it built-in so it automatically loads on systems booting in PowerNV mode. One of the reaons is to save power by default (the default cpufreq governor is ondemand). That cpufreq driver fails gracefully on other (non IBM, OPAL) powerpc platforms that don't have the expected files in the device-tree (see [2]). A patch will be sent to the kernel-team mailing list.
