Is there a way to force the driver into a specific state? 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.
