ok, that I dont know...
as for the text, I agree that for the time being is should say "only the first generation hardware" or similar, I'd guess most people wouldn't know what AMS means... although alot wouldnt know the difference between first and 2nd gen anyway.
Maybe we change the whole thing to just say "Some Sansa e200, c200, etc (click here to find out if yours works)" and link to rbutil wtih quick insturctions to check?
