I believe that when rumors of the initial Courtois & Pieprzyk work first 
made the
rounds (Crypto '01?), it was "whispered" that their attack only applied to 
(or was
simply more efficient at?) the 2 larger key sizes, but not to/at 128. The 
situation
now seems to be much more complicated. See, for example:
