ALSA: hda - iMac 9,1 sound patch.

This is an updated patch for the Apple iMac 9,1 model to add sound.
Original patch posted here:
http://article.gmane.org/gmane.linux.alsa.devel/61361/match=

I have been using this patch for a while now
and have to say it works vary well, except for a few minor 
things:

	With the iMac 24-inch 3.06GHz Intel Core 2 Duo
	everything seems to be working as it should,
        although I have not looked into the microphone
	(never really use one, nor have any apps to test,
	my guess is it doesn't work, or I never figured out how
	to get it to work).

	With the iMac 24-inch 2.66GHz Intel Core 2 Duo
	everything is the same as with the above machine 
	except I'm hearing a light scratchy/distortion noise
	come out of the speakers when using headphones(above machine
	does not do this).

Other than that the sound level is great(especially with good Dj headphones).
