Broadcom does not support Linux with open source drivers or with information which will support them. Generally, for wireless especially, you use ndiswrapper to use Broadcom drivers (it runs the Windows drivers). Just about any distro runs ndiswrapper but Ubuntu is usually easier to get it running out of the box. So expect a few problems, period, and Broadcom has heard about them (they recently sent engineers to some industry gathering where most of the speeches blasted them for this).
