I want you to try something that is somewhat different.

I went over that document once more:

PCI table verification.
That's your chip and driver:
14e4:4315 supported 2.6.33 and later (PIO mode) BCM4312 b/g LP b43

You have the required kernel ?
[root at localhost jb]# uname -r

Instead of following the info under Fedora, I checked Mandriva as well and
discovered some similarities to your chip:
device firmware installation
There are different versions of firmware and tools you may need: 
b43   Linux-2.6.31 and newer, compat-      ....  GO
      wireless-2.6 package, current GIT trees -              
      for LP-PHY cards 
When you press the GO link you get to:
You are using the b43 driver with an LP-PHY card (e.g. BCM4312)
Install b43-fwcutter, then use version of Broadcom's proprietary
driver. (The tarball is mislabeled as "", but it is actually
Let's do the down load and extraction operation:
tar xjf broadcom-wl-
cd broadcom-wl-
$ su
# b43-fwcutter -w /lib/firmware/ wl_apsta.o

The extraction worked for me !
Well, try it and reboot now.

Your dmesg should be more informative than the one you passed to us
