macvidcards mods the cards so you have a proper boot screen.
my card isnt connected to a monitor, just using it for CUDA, so theres no need if you are running headless.
many people dont care, but if you want you can also send them your card to be modded
10.7.4 you have to install the nvidia driver for the quadro4000.
in 10.8 i dont think you have to install anything
