Mobility HD 3450..

[MatthewRuddy]

Hey all.. I've asked everyone about this yet received no proper answer.. So I've come here baring the same question..

What is the story with the HD 3450 Mobility card? What specifically is causing it and other Mobility cards from not working? What makes them so diffrent from Intel onboard graphics? Or their PIC-E counterparts?

Has anyone managed to get full 1440x900 resolution from a Dell Studio 15 laptop with this Mobility Radeon HD 3450 card? Or a laptop of a similar specification? This is all I am looking for..

Have they given up on these cards? Is there no possible way to get them working? Really, I find no reason to have Leopard on my Dell laptop if there is no graphics support..
