As already noted earlier in this thread, if you disable

hint.p4tcc.0.disabled=1
hint.acpi_throttle.0.disabled=1

then the kernel does not even expose expose those silly minimum
"frequencies", and your problem goes away without patching powerd.

A more reasonable and simpler patch would be to disable the two
offending throttling drivers by default, I really cannot see a single
reason why do we need them at all, less why they are enabled.
