No. The problem is Apple wanted to have its name on it. Dell, HP, Sony, they all won't adopt a technology, even if it's superior, that carries an apple in its name. FireWire did well - no Apple in the name included.
The card still has the power connector that was used to power the monitor through ADC. It seems they used that to provide some extra juice to the card. Did you see that area with discret stuff behind the cooler. Looks like voltage regulation.
