Is there some sort of electrical gate that snaps open when the 12v line actually reaches 12v, or is it just driven by a capacitor as Duckie suggests? I'm curious to know more about how this works?
Yes, there are. However, a cap would be simplest way of doing it. Also, I am not sure the signal voltage is 12v.

Not sure why anyone would want to shorten the delay. It would make sense to me to make that delay as long as possible.
Capacitor.... not a resistor.
For layman, a capacitor would stop voltage from flowing through the line. However, the voltage starts to "leak" through as the cap charges. Once the cap is full, the full volage goes through. This should work for a constant DC signal and there is a threshold voltage for the signal on the motherboard.
