The quote first refers to CS25.1309 and then copies a subparagraph of CS25.207. Both requirements have been referenced and discussed more than once on the various parts of the AF447 thread. I'm not an expert on the certification of the A330, but I recall that the certification basis contains an exception (SC or ESF or IP, I don't recall) that may relate to paragraph 25.207. First of all, it must be understood that 25.207 and most other requirements of CS25 Subpart B 'Flight' must be met with all airplane systems and equipment functioning as designed. Failure conditions, such as reversion to alternate law, are considered under paragraph 25.1309 on the basis of their probability of occurrence and their effect on the safety of continued flight and landing. In normal law, the A330 does not have stall warning as intended by CS25.207. I presume that requirement has been waived in consideration of the high-angle-of-attack protection in normal law.

Ok .. so nothing new added .. question not answered.
Be sure (for those who want an answer .. of course) that this question will be on the center of discussions and answered .. but in another room than this one
Personally I have a doubt about the implication of the different flight laws of A330 for be an (good argument) reason for a derogation of the stall alarm certification.
Certification "a la carte" ?
Seem's .. the "menu du jour" is better
