    Len, I've tentatively traced this down to the addition of the ACPI
    wakeup_devices module that went into the kernel via ACPI 20040715.

    From a quick look at the code, the wakeup devices get set at boot, but on
    shutdown, they don't get unset. Is this intentional?

    Any clues, ideas, or suggestions?
