Description SAKIYAMA Nobuo 2001-07-04 18:00:14 UTC 
	original ICH sound driver(sys/dev/sound/pci/ich.c) lacks
	suspend method, so when a system are suspended & resumed
	while playing sounds, kernel is hung.

Fix: I wrote a patch.
	This patch also eliminates unnecessary switch statements,
	and consumes less power when suspending.
How-To-Repeat: 	You start up a kernel enabling APM.
	Then you play sound-tracks by any player program.
	Before ending the sound, you suspend the machine
	by switches or zzz (8) command.
	Finally, you try to resume the machine.

The device now has a suspend function. If it doesn't work for you please 
open a new PR. 

Thanks for submitting a patch back then though.
