  30  * Driver for extra ACPI-controlled gadgets (hotkeys, leds, etc) found on
  31  * recent Asus (and Medion) laptops.  Inspired by the acpi4asus project which
  32  * implements these features in the Linux kernel.
  33  *
  34  *   <http://sourceforge.net/projects/acpi4asus/>
  35  *
  36  * Currently should support most features, but could use some more testing.
  37  * Particularly the display-switching stuff is a bit hairy.  If you have an
  38  * Asus laptop which doesn't appear to be supported, or strange things happen
  39  * when using this driver, please report to <acpi@FreeBSD.org>.
