My laptop was one of those with the snd_ich problems after S4_BIOS resume.
It was caused by bad BAR restores as the problem could be fixed by simply
setting the PCI registers as they were before suspend.

I can acknowledge that it now works without any twiddling.
Listening to some music right now after I have just suspended :-)

Like said before, the PCI changes didn't have any influence on my "S3 
immediate resume after suspend" issue.
