Right this is what's on there (I didn't produce links for things which people had asked me to compile and that I wasn't going to [think about] supporting).
I can't really remember why half of this stuff is on there but it might be useful for someone (the tar.gz files generally contain the build tree including source and the binaries; e.g. before 'make install' has been run, but some of them are binary only and are just tar.gz because I couldn't be bothered to make an ipk):
