Under most of the cases, powernow kernel module is outdated, you
should use acpi p-states if possible.
It looks like acpi p-states do exist, but lacking CPU driver.  Could
you post the dmesg?
Or at least post the lines like following one (usually at the beginning of ):
CPU: AMD Phenom(tm) 9550 Quad-Core Processor (2200.09-MHz K8-class CPU)
  Origin = "AuthenticAMD"  Id = 0x100f23  Stepping = 3
