I have a Scorpio Black with sensor on a 17" ubMBP (Early 2009) with no conflicts. From the research I've done, I believe that conflict was limited to an earlier, specific model of MacBook.
Interestingly enough, this was a warranty swap for a non-sensor model. I was a bit unsure about it, but since I hadn't seen any conflict reports of late, I'd try it. No troubles at all. I even went so much as to trip it (GENTLY lowering the MBP in mid-air, but quickly enough to cause enough acceleration to trip the sensor). I could hear the head unload just fine and no KPs.
That all said, get the one without - the MacBook Pro has its own drop sensor (the Sudden Motion Sensor (SMS)), so if the drive is more expensive, it's a waste. The drive's sensor would be moot.
