Using SpeedStep for Centrino with decoding the speeds and voltages (CONFIG_X86_SPEEDSTEP_CENTRINO_ACPI) will not yield any output during boot regarding cpufreq at all and the battery useage is heavy. ACPI is enabled. mvh, A -- Alexander Hoogerhuis | alexh@boxed.no CCNP - CCDP - MCNE - CCSE | +47 908 21 485 "You have zero privacy anyway.
