I'm a newbie on Freebsd and I'm trying the 5.3 Release on a Acer Aspire 1513lmi/amd64. I've debugged my dsdt for the acpi and it seem working correctly but I don't be able to scale the cpu frequency. I read that the powernow-k8 is not implemented on the Freebsd systems ( I think this is correct). Is there a method to control the cpu frequency? Thank you
