Or to manually add a state? I still cannot access C0 (max frequency), C4, or C5 power saving states, that are all supposed to be supported by the Intel Centrino Core Duo CPU Can someone point me to the code that determines the voltage / amperage pairings for CPUs in power saving mode? Is this handled by the ACPI bios (bios function call), or does the kernel directly affect the power setting? I'd like to take a look and see what's going on.
