All kinds of people having problems, not only with the old AirPort  
cards with Broadcom chipsets, but third party wireless with Broadcom  
chipsets as well.

Follow these instructions _EXACTLY_ to downgrade, or you will break  
your system.

Remove /System/Library/Extensions/AppleAirPort.kext (version 3.4.4)  
along with AppleAirPort2.kext (version 4.0)

Download and install Pacifist. If your networking is broken connect  
with ethernet cable or you will have to download from another  
computer, burn to a CD, and install on the affected Mac. Pacifist can  
be gotten here ( http://www.charlessoft.com/ )

Insert your Tiger installation DVD and using Pacifist open the / 
System/Installation/Packages/OSInstall.mpkg file on the DVD. In  
Pacifist under the Contents of Essentials.pgk browse to the /System/ 
Library/Extensions directory and install the following kernel  
extensions using the Install button in the toolbar of Pacifist:

AppleAirPort.kext (version 3.4.4, same as the new one in 10.4.2),
AppleAirPort2.kext (version 3.5), and
AppleAirPort3.kext (version 3.6).

You'll now be running the old version of the AirPort drivers (kernel  
extensions).  I've successfully downgraded about a dozen already with  
a 100% success rate.
