i also have a acer ferrari 4005. i've tried the stock 4318 card as well as replacing it with a 4306 card and an intel card, none of which work. all of these cards work with ubuntu on other computers. there is a serious problem with interrupts on edgy amd64 and the acer ferrari which cause the mini-pci bus (and many other things, like the power button) not to work.
