409 the bay while buses are still active), etc.
410
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.
415
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.

439 bad interactions with X.org.
440
441 NOTE: access to this feature is limited to processes with the

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.
457
458 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
459 unlikely to need NVRAM polling in their latest BIOS versions.

620 This driver adds support for access to certain system settings
621 on "legacy free" Toshiba laptops. These laptops can be recognized by
622 their lack of a BIOS setup menu and APM support.
623
624 On these machines, all system configuration is handled through the
625 ACPI. This driver is required for access to controls not covered
626 by the general ACPI drivers, such as LCD brightness, video output,
627 etc.
628
629 This driver differs from the non-ACPI Toshiba laptop driver (located
630 under "Processor type and features") in several aspects.
631 Configuration is accessed by reading and writing text files in the
632 /proc tree instead of by program interface to /dev. Furthermore, no
633 power management functions are exposed, as those are handled by the
634 general ACPI drivers.
635
636 More information about this driver is available at
637 <http://memebeam.org/toys/ToshibaAcpiDriver>.

651 and re-enables it when the switch is set back to the 'on'
652 position.

668 been stabilized.
669

743 This option provides a means to manipulate Isolated Memory Regions.
744 IMRs are a set of registers that define read and write access masks
745 to prohibit certain system agents from accessing memory with 1 KiB
746 granularity.
747
748 IMRs make it possible to control read/write access to an address
749 by hardware agents inside the SoC. Read and write masks can be
750 defined for:
751 - eSRAM flush
752 - Dirty CPU snoop (write only)
753 - RMU access
754 - PCI Virtual Channel 0/Virtual Channel 1
755 - SMM mode
756 - Non SMM mode
