The basic idea (as I remember which could very well be wrong) is that the short ones are power, the long ones are ground, and all the others are bus signals. The idea being that when you plug in a module, you connect grounds first, then signals, then power everything up. The process reverses when the module is removed.
Actually the long ones are power and ground, the medium ones the signals, and the short ones the "card detect" pins.
That way when you insert the card, the power and ground are connected first, then the signals, and finally, when the card is nearly fully seated, the card detect lines. The card detect lines let the Visor know that a new Springboard has been inserted.
Reverse everything for removal.
