 413
 414           If this option is enabled, ThinkPad-ACPI will export an ALSA card

 421
 422           All IBM models have both volume and mute control.  Newer Lenovo
 423           models only have mute control (the volume hotkeys are just normal

 452           Overriding LED state on ThinkPads can mask important

 455           the bay while buses are still active), etc.
 456
 457           LED control on the ThinkPad is write-only (with very few
 458           exceptions on very ancient models), which makes it
 459           impossible to know beforehand if important information will
 460           be lost when one changes LED state.

 486

 501           need to do NVRAM polling to support any of the hot keys you use,

 504           ThinkPads T40 and newer, R52 and newer, and X31 and newer are
 505           unlikely to need NVRAM polling in their latest BIOS versions.
 506

 634
 635           ACPI-WMI is a proprietary extension to ACPI to expose parts of the
 636           ACPI firmware to userspace - this is done through various vendor
 637           defined methods and data blocks in a PNP0C14 device, which are then
