building 11.1-stable on 10.4 ppc system

[Jukka Ukkonen]

Has anyone successfully built 11.1-stable or any other 11 series kernel
on a 10.4-stable ppc system?
I mean is there a reasonable possibility to build a functional 11.1 environment,
though, the 11.1-release CD and DVD images are both broken?
Will I need any special steps in addition to the usual...

make kernel-toolchain
make buildkernel
make installkernel

Will the old standalone boot branch (loaders, boot blocks, etc.) work or 
will they have to be updated as well at the same time with the kernel?
What about the tools needed to build them?
