That was exactly my point. It's not really a 'kickdown' switch as it is the WOT (wide open throttle) switch. What the computer does with that information is different based on gear and speed, and I am 98% certain it raises the shift points.

It raises the shift points. All newer bmw automatics have this feature (Well, okay, I THINK they all do...) - the car will shift around redline; in rare instances you might even pass redline if you WOT close to a gear lower when you downshift...
When in first and it is depressed, the car raises the shift point to right below the redline as opposed to about 4500 rpm when the switch is not in.
When you are cruising at lets say 40 mph and you stab the gas pedal, thus pushing the switch in, the car will downshift to probably 2nd, and will then hold it in second until it reaches it's high shift-point. If you still keep it in, it will go to redline in 3rd and shift etc.
