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>.
