Just another way for the Fed to try and calm the markets out of panic mode. You can be sure that Bernanke made the call to the heads of these banks and said "Ladies and gentlemen, we have a potential crisis at hand, and we need your help to alleviate the situation". I cannot recall a time that ANY major bank made a public announcement that they used the discount window. It actually has me more concerned that they made the statements. Then again, this may be a new tactic for the Fed - manipulation of the big money center banks to say "all is well" - might work, might not.
