>Description:

	After using the sound-device (clcs) on my ThinkPAD20m
	it something failes to write to AC97 registers when
	un-suspending it (when it wakes up after a `zzz').

	It looks like it failes when it writes the shadow registers
	back to the AC97-thingy.

>How-To-Repeat:

	Use your Thinkpad 20m to play swedish radio with realaudio or
	play mp3's with mpg123. Then after som time computer locks up
	when unsuspending it (not really but they busy loop takes too
	long time)

>Fix:
	
	Beat the clcs chip harder when suspending/unsuspending ?
