374
375	  LED control on the ThinkPad is write-only (with very few

403	  bad interactions with X.org.
404
405	  NOTE: access to this feature is limited to processes with the

566	---help---
567	  This driver provides support for extra features of ACPI-compatible
568	  ASUS laptops. As some of Medion laptops are made by ASUS, it may also
569	  support some Medion laptops (such as 9675 for example).  It makes all
570	  the extra buttons generate standard ACPI events that go through
571	  /proc/acpi/events, and (on some models) adds support for changing the
572	  display brightness and output, switching the LCD backlight on and off,
573	  and most importantly, allows you to blink those fancy LEDs intended
574	  for reporting mail and wireless status.
575
576	  Note: display switching code is currently considered EXPERIMENTAL,
577	  toying with these values may even lock your machine.
578
579	  All settings are changed via /proc/acpi/asus directory entries. Owner
580	  and group for these entries can be set with asus_uid and asus_gid
581	  parameters.
582
583	  More information and a userspace daemon for handling the extra buttons
584	  at <http://acpi4asus.sf.net>.
585
586	  If you have an ACPI-compatible ASUS laptop, say Y or M here. This
587	  driver is still under development, so if your laptop is unsupported or
588	  something works not quite as expected, please use the mailing list
589	  available on the above page (acpi4asus-user@lists.sourceforge.net).
590
591	  NOTE: This driver is deprecated and will probably be removed soon,
592	  use asus-laptop instead.

614	---help---
615	  This driver adds support for access to certain system settings
616	  on "legacy free" Toshiba laptops.  These laptops can be recognized by
617	  their lack of a BIOS setup menu and APM support.
618
619	  On these machines, all system configuration is handled through the
620	  ACPI.  This driver is required for access to controls not covered
621	  by the general ACPI drivers, such as LCD brightness, video output,
622	  etc.
623
624	  This driver differs from the non-ACPI Toshiba laptop driver (located
625	  under "Processor type and features") in several aspects.
626	  Configuration is accessed by reading and writing text files in the
627	  /proc tree instead of by program interface to /dev.  Furthermore, no
628	  power management functions are exposed, as those are handled by the
629	  general ACPI drivers.
630
631	  More information about this driver is available at
632	  <http://memebeam.org/toys/ToshibaAcpiDriver>.
