Hello, I've just released oldworld-deb - a boot floppy that can boot Debian Installer from the CD on OldWorld PowerMacs, such as Power Macintosh 8200.
It's based on miBoot, Linux kernel, kexec-tools, uClibc and a simple init program written in C. You can get the source and also a pre-built image here: https://github.com/ondrej-zary/oldworld-deb -- Ondrej Zary
