366           If this option is enabled, ThinkPad-ACPI will export an ALSA card

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

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

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

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