If you want to use open software for everything, there is no way to operate the
BCM4312 802.11b/g card with a PCI ID of 14e4:4315. The open-source driver b43
needs the firmware extracted with fwcutter, and that firmware is not open
source. The Broadcom hybrid driver is the only other option; however, it is
worse as the driver code and the firmware are both closed source.

If you want to use the card, you will need to find a way to relax the
restriction on closed-source firmware or find another distro.

I do not like the idea of having to use closed-source firmware, but at least it
cannot cause your kernel to go crazy and destroy your file system the way a
closed-source driver could.
