I think so. The machines we have in the OSI blacklist all appear to have the SAUM method, so I think we can take your patch and drop the blacklist.

I can't see any way this would cause problems, except in the case where the method exists but doesn't do anything. I'd be surprised if that's a real problem. > (Even if it works, don't apply this patch for 2.6.40 as it stands > because the ALSA change notification on KEY_MUTE is crap and should at > least ignore key release events.)
