Does it make sense to load the speedstep-centrino module at boot time, then figure out how the acpi event mechanism works, and use that to adjust the laptop mode and power policy modes based on the power cable status? Aslo, if you give the centrino module a range of frequencies, how does it decide what frequency to run the cpu at? Thanks, Philip
