The contents of the whitelist are irrelevant. My laptop needs this 
functionality, but I haven't bothered to send you a whitelist entry, in part 
because I don't use s2ram.

Regardless of that, if you had read the whole comment (you've deleted half of 
it), you would have noticed that I ended up changing my mind and instead 
saying "Why not just delete the __setup now, or at least put it in the 
deprecated file?"
