Can you change this one to:
"cpufreq driver for Maple 970FX/970MP boards");
It looks for both those CPUs in probe.

This one's tricky, because it probes based on the device tree, though it
is restricted to CONFIG_POWERNV. It also supports non-IBM CPUs in theory
at least. Maybe something like:
"cpufreq driver for IBM/OpenPOWER powernv systems");
cheers
