From f5d8b746903f5367297004175baffffdc7d01824 Mon Sep 17 00:00:00 2001
From: phk <phk@FreeBSD.org>
Date: Wed, 26 Mar 2008 22:02:51 +0000
Subject: Further cleanup of sound generation in syscons:

The timer_spkr_*() functions take care of the enabling/disabling
of the speaker.

Test on the existence of timer_spkr_*() functions, rather than
architectures.
