Starting, I have to sorry for my english, because it's not my fist language. Well, I installed Vista x64 on my new MacBook (I bought it a week ago) and works fine, except of the installation of Boot Camp. When I try to install it, the program says that it's not the correct model of computer for install it, so I had to install the x64 drivers manually from the leopard DVD. Another thing, for the display driver, I had to download it from the intel webpage, for a gm965 chipset family (mine is gma 3100). About hardware control, by a lack of apple's programs, Windows should control the energy management (except, in my case, the screen brightness). Hope that I could have helped you!!
