I have strange notebook here, and that one only works reasonably with APM (with ACPI: no network IRQs, random mouse problems, random shutdowns due to bad temperature readings). I'd suggest to leave old driver there (possibly let me clean it up ;-)))), and create new powernow-k8-acpi, or powernow-acpi or something like that. Pavel -- When do you have heart between your knees?
