Please tell me if there is a way to: 1. switch the kernel driver in use, back to non proprietary, or disable the one now in use. 2. tell me how to actually get the wireless device/devices working.

Now this is what I get when I follow the guidelines laid out here:Installing Broadcom Wireless Drivers
I get this in the terminal and cannot continue further. perhaps I can disable the kernel driver before attempting to repair?
