This is an apt repository for Jon Dowland's packages. You should find them all in source here, and some in binary, where I've built them (usually for i386 sid).
Add the following to /etc/apt/sources.list:
deb http://debian.halfcoded.net/ binary/ deb-src http://debian.halfcoded.net/ source/
As it is possible I have not built an appropriate binary package for you, I suggest always building from source, e.g.
$ fakeroot apt-get -b source bsp $ sudo dpkg -i ./bsp*deb
