From 286c2bdbdf6b926fab7e57f77cbce263c0f5f1c2 Mon Sep 17 00:00:00 2001
From: Miod Vallat <miod@cvs.openbsd.org>
Date: Mon, 29 May 2006 20:23:14 +0000
Subject: Add support for the audio volume keys found on many laptops' builtin
 keyboard. These specific keys are posted to a kernel thread which will issue
 mixer commands if an audio device exists.

Written by Alexey Vatchenko <avv , mail zp ua> with tweaks by deraadt@ and I.
