 Привет!
 
 В шестерке слегка причесали юзеровские ручки для кручения ACPI
 (sysctl) и документировали в man acpi:
 
        hw.acpi.disable_on_reboot
 Disable ACPI during the reboot process.
 Most systems reboot fine with ACPI still enabled, but some require
 exiting to legacy mode first.
 Default is 0, leave ACPI enabled.
 
        hw.acpi.handle_reboot
 Use the ACPI Reset Register capability to reboot the system.
 Default is 0, use legacy reboot support.
 Some newer systems require use of this register, while some only work
 with legacy rebooting support.
 
        hw.acpi.lid_switch_state
 Suspend state (S1-S5) to enter when the lid switch (i.e., a notebook
 screen)
 is closed.
 Default is NONE (do nothing).
 
        hw.acpi.power_button_state
 Suspend state (S1-S5) to enter when the power button is pressed.
 Default is S5 (power-off nicely).
 
        hw.acpi.reset_video
 Reset the video adapter from real mode during the resume path.
 Some systems need this help, others have display problems if it is enabled.
 Default is 0 (disabled).
 
        hw.acpi.s4bios
 Indicate whether the system supports S4BIOS.
 This means that the BIOS can handle all the functions of suspending the
 system to disk.
 Otherwise, the OS is responsible for suspending to disk (S4OS).
 Most current systems do not support S4BIOS.
 
        hw.acpi.sleep_button_state
 Suspend state (S1-S5) to enter when the sleep button is pressed.
 This is usually a special function button on the keyboard.
 Default is S3 (suspend-to-RAM).
 
        hw.acpi.sleep_delay
 Wait this number of seconds between preparing the system to suspend and
 actually entering the suspend state.
 Default is 1 second.
 
        hw.acpi.supported_sleep_state
 Suspend states (S1-S5) supported by the BIOS.
 
        S1
 Quick suspend to RAM.
 The CPU enters a lower power state but most peripherals are left running.
 
        S2
 Lower power state than S1, but with the same basic characteristics.
 Not supported by many systems.
 
        S3
 Suspend to RAM.
 Most devices are powered off and the system stops running except for
 memory refresh.
 
        S4
 Suspend to disk.
 All devices are powered off and the system stops running.
 When resuming, the system starts as if from a cold power on.
 Not yet supported by FreeBSD unless S4BIOS is available.
        S5
 System shuts down cleanly and powers off.
    
        hw.acpi.verbose
 Enable verbose printing from the various ACPI subsystems.
