I never tried Alt-SysRq-b and have not seen the spontaneous power-off, but the percentage correct boots and relationship with the sound driver are spot on. I worked around the sound driver relationship by using a very low power save setting so I can virtually count on it being disabled when I suspend. I'll give your patch a go and report the results. Nice work!
