Ok to begin with I am so unhappy with Snow Leopard that i really really need to roll back to Leopard but we are all aware of Apple's paranoid downgrade-fobia so yes following the designated paths we are not able to install earlier OS's on later machines. But lets say I am so determined that I bought a Leopard DVD and succeeded installing it on a new Macbook Pro 2011 (which came with Snow Leopard 1.6.6) using target disk mode. Would it recognize and make use of the new hardware? For instance the new turboboost processor? the new thunderbold port? the video card(s)? (and what not)... Are drivers for such hardware separately obtainable? If yes does anyone know how and where?
