That looks good. For what it is worth, the openSUSE script would be a good 
starting point for network installations. It only uses standard utilities, and 
the only assumption it makes is that b43-fwcutter is available.

The off-line firmware installation is more important. File 
http://www.lwfinger.com/b43-firmware/no_net_install_bcm43xx_firmware.tar.bz2 
handles the problem, but only for a single version of the firmware.

I think you are ready to contact the distros.
