Unfortunately for the L03, it did not work for me. I got the light gray screen with the dark gray apple in the middle. Then the screen goes black when the install screen to choose language is supposed to come up. I tried to install Switch ResX with Leopard and Leopard would not start up. I had to switch back to the original screen.
I just wanted to add I have the earler pre Santa Rosa Core 2 Duo macbook pro, maybe that is the difference.
Noone here is running the 1920x1200 display on a Santa Rosa MBP as far as I know. The Santa Rosa has a different display casing and uses LED backlighting -- and I imagine due to how new those MBPs are, there are fewer people willing to put their MBP into surgery mode to dabble into the realm of HD displays at the moment.
