I am pretty sure the normal kernel driver supports 4312s. (kernel.org
is still out, so I can't easily double check this right now.)
I am not sure if the open firmware supplied by Fedora will work in
4312s though. The site's web page doesn't specifically claim to work
with that model.

So at worst, you should be able to get a copy of needed firmware (Broadcom's
firmware is not redistributable) and not mess with the driver. There are
instructions on how to get a copy of Broadcom's firmware here:
