The BroadcomWirelessChipset made by Broadcom is a one of the more relatively common WirelessChipsets available today. It is shipped by a wide range of companies.
Previously there was not good support for this in the LinuxKernel but more recent versions (>= 2.6.17) are adding support.
You will need to extract firmware from a MicrosoftWindows driver by using a tool called fwcutter available from 
http://developer.berlios.de/project/showfiles.php?group_id=4547 or in DebianLinux as a package called bcm43xx-fwcutter.
Run this program and put the extracted firmware into <pre>/lib/firmware</pre> - you should change the owner and group to root.
