I understand your frustration, but I want you to know that I found a way to use my PowerMac G5 in these last two days.
Basically I am using Debian Sid PPC64 with this extra repository: http://repo.powerprogress.org/ Both Firefox and mpv are working. I was even able to use wifi after manually compiling the package for b43-fwcutter. Regards > I already wiped my ppc64 installation a few days ago in favor of the > powerpc variant.
