Install B43 drivers without internet connection

http://askubuntu.com – I've spent all day trying to solve this with no results. The problem I have is that my Dell Vostro 1500 has defective Ethernet. It can't connect to Ethernet for some reason, most probably a hardware problem, so I need to install the drivers without having internet in the computer in which it's getting installed. Any solutions that require a second computer with Linux won't work. This is being typed from OS X and the other computer I have is the computer with the problem. Running lspci I get: 00:00.0 Host bridge: Intel Corporation Mobile PM965/GM965/GL960 Memory Controller Hub (rev 0c) 00: (HowTos)
