It's impossible to use the dual link DVI connector to drive two independent displays. It's only attached internally to a single display controller, that's point number one. Dual link DVI also works by sending odd pixels to one link and even to the other, so even if any type of "splitter" were made it would be rather useless. Because, it's only a single display. Back to point number one.

If someone wants multiple displays on their Powerbook, they should seek out the company DigitalTigers ( http://www.digitaltigers.com ). Tell them I sent you and that I should really get a little kickback for the sales referral. (I'm serious).
