do you have the card or you plan to get it?
if you have it, just pop the files in...
if you don't have it, dont risk it..
i don't believe on that power draw revisions, the only reason to make a new card from this websites is to make it unblocked on the console, old costumers get the card blocked on the console and they can sell it again..
there is no seem kernel update... which means, if it was blocked, there is no change it gonna to work unless you was on firmware <9.2 and had gateway.. but you dont...
