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

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

405           Overriding LED state on ThinkPads can mask important

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

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

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

576           other kernel space drivers.
578           This driver is a required dependency to build the firmware specific
