 323           For more information about this driver see

 325           <http://ibm-acpi.sf.net/> .

 329           Extra functionality will be available if the rfkill (CONFIG_RFKILL)
 330           and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
 331           Note that if you want ThinkPad-ACPI to be built-in instead of
 332           modular, ALSA and rfkill will also have to be built-in.

 346
 347           If this option is enabled, ThinkPad-ACPI will export an ALSA card
 348           with a single read-only mixer control, which should be used for
 349           on-screen-display feedback purposes by the Desktop Environment.
 350
 351           Optionally, the driver will also allow software control (the
 352           ALSA mixer will be made read-write).  Please refer to the driver
 353           documentation for details.
 354
 355           All IBM models have both volume and mute control.  Newer Lenovo
 356           models only have mute control (the volume hotkeys are just normal

 385           Overriding LED state on ThinkPads can mask important

 387           the user into damaging the hardware (undocking or ejecting
 388           the bay while buses are still active), etc.
 389
 390           LED control on the ThinkPad is write-only (with very few
 391           exceptions on very ancient models), which makes it
 392           impossible to know beforehand if important information will
 393           be lost when one changes LED state.
 394
 395           Users that know what they are doing can enable this option
 396           and the driver will allow control of every LED, including
 397           the ones on the dock stations.
 398
 399           Never enable this option on a distribution kernel.

 413           display state, video output devices in use, whether there is a X
 414           server running, phase of the moon, and the current mood of
 415           Schroedinger's cat.  If you can use X.org's RandR to control
 416           your ThinkPad's video output ports instead of this feature,
 417           don't think twice: do it and say N here to save memory and avoid

 419
 420           NOTE: access to this feature is limited to processes with the
 421           CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
 422           where it interacts badly with X.org.

 432           Some thinkpad models benefit from NVRAM polling to detect a few of
 433           the hot key press events.  If you know your ThinkPad model does not
 434           need to do NVRAM polling to support any of the hot keys you use,
 435           unselecting this option will save about 1kB of memory.
 436
 437           ThinkPads T40 and newer, R52 and newer, and X31 and newer are
 438           unlikely to need NVRAM polling in their latest BIOS versions.
 439
 440           NVRAM polling can detect at most the following keys: ThinkPad/Access
 441           IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
 442           Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).

 548
 549           ACPI-WMI is a proprietary extension to ACPI to expose parts of the
 550           ACPI firmware to userspace - this is done through various vendor
 551           defined methods and data blocks in a PNP0C14 device, which are then
 552           made available for userspace to call.
 553
 554           The implementation of this in Linux currently only exposes this to
 555           other kernel space drivers.
 556
 557           This driver is a required dependency to build the firmware specific
 558           drivers needed on many machines, including Acer and HP laptops.

 601           On these machines, all system configuration is handled through the

 605
 606           This driver differs from the non-ACPI Toshiba laptop driver (located
 607           under "Processor type and features") in several aspects.
 608           Configuration is accessed by reading and writing text files in the
 609           /proc tree instead of by program interface to /dev.  Furthermore, no
