Another werewolf question

I was reading some of the posts about the treatment of werewolves by 
the MoM and the agencies that deal with them.  

Besides Wolfsbane Potion, there is another possible cure and I am 
wondering how it can be brought to light in order to save Sirius.

In CoS, Lockheart has Harry act out a scenario in which he 
supposedly performed a charm that turned a werewolf back into a 
normal human again.  Of course, we later learn that Lockheart didn't 
do any of the things he wrote about himself, but that someone else 
did.  He just made it impossible for those people to go on fighting 
the Dark Arts when he altered their memories.  (IMO, that makes him 
an even worse, selfish baddy--to deprive wizardkind of people who 
can keep the world safer just so he can sell books and take credit 
for himself!  Harumph!) ;-)

I'm pretty confident that someone will realize this--I'm betting on 
Hermione!--and cure Lupin so that he can be more effective in the 
fight against Voldy.  

Can anyone venture a guess as to who can break the memory charms and 
how?  Also, who might be powerful enough to do the charm on Lupin?  
It seems natural for the task to fall to Sirius, but is that just 
too obvious?  

looking forward to hearing anyone's comments on this!
