At first, are you sure going with ACPI didn't help?  If that is the
case, I don't see the difficulty to do what you ask, especially if you
have already done such hack (ACPI is a fallback, so unless your laptop
is in a DMI blacklist, hacking powernow_decode_bios() should work).

I'm afraid nobody will integrate that in mainline.
