368           If this option is enabled, ThinkPad-ACPI will export an ALSA card
369           with a single read-only mixer control, which should be used for

376           All IBM models have both volume and mute control.  Newer Lenovo

409           the bay while buses are still active), etc.
411           LED control on the ThinkPad is write-only (with very few
412           exceptions on very ancient models), which makes it
413           impossible to know beforehand if important information will
414           be lost when one changes LED state.
416           Users that know what they are doing can enable this option
417           and the driver will allow control of every LED, including
418           the ones on the dock stations.
420           Never enable this option on a distribution kernel.

453           Some thinkpad models benefit from NVRAM polling to detect a few of
454           the hot key press events.  If you know your ThinkPad model does not
455           need to do NVRAM polling to support any of the hot keys you use,
456           unselecting this option will save about 1kB of memory.
458           ThinkPads T40 and newer, R52 and newer, and X31 and newer are
459           unlikely to need NVRAM polling in their latest BIOS versions.
461           NVRAM polling can detect at most the following keys: ThinkPad/Access
462           IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
463           Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).

571           ACPI-WMI is a proprietary extension to ACPI to expose parts of the
572           ACPI firmware to userspace - this is done through various vendor
573           defined methods and data blocks in a PNP0C14 device, which are then

577           other kernel space drivers.
