[PowerPc] backports repositories

[Kerri]

Hi
I'm using Ubuntu Hardy Heron 8.04 on an iBook G4 1,2Ghz, and I've got a problem: I can't use backports repository: most servers haven't ppc binaries, and the few that I found with a powerpc-binaries folder (like http://ubuntu.nad.go.id/repo/ubuntu/ ) aren't working: when I try to update packages list after add them, I've got this error:

W: Impossible de récupérer http://ubuntu.nad.go.id/repo/ubuntu/...c/Packages.bz2 Somme de contrôle de hachage incohérente

So, any one now where can I found a valid backport depositories for a PPC Hardy?
Thanks
