    This is indeed related to CPUIDLE.

    Tilman: Can you configure CONFIG_CPU_IDLE in your config (under Power
    Management option) and double check that the frequency part works after
    that.

    Andrew: Adam Belay sent a recent patchset on linux-pm and linux-acpi and
    one of the patches of that addresses this issue (CPUIDLE: load ACPI
    properly when CPUIDLE is disabled). Those patches should come to mm soon
    through acpi-test.

    Thanks,
    Venki
