To check if mixer settings can be loaded/saved, /proc/devices is grepped
for a sound entry, but this is done inconsistently in different init

In /etc/rc.d/rc.sysinit, where the settings are loaded, it says at line
  grep -q "14 sound" /proc/devices 2>/dev/null

And in /etc/rc.d/init.d/halt, where the settings are saved, it says at line
  grep -q "\(sparcaudio\|sound\)" /proc/devices

As the second method seems more portable (if sparcaudio is really used?
can't check since I have no sparc), I think it would be the best to also
use this for the first case.

Maybe it's better to move this "detection" to /etc/rc.d/init.d/functions,
ie something like:

checksound {
  return grep -q "\(sparcaudio\|sound\)" /proc/devices 2>/dev/null

which could then be used consistently in all init scripts.
