powerpc vs ppc build

[Jeff Angielski]

Is there a summary of the differences between the ppc and powerpc builds
for the 2.6 kernels?  Or something describing what the community, in
general, is trying to fix/address with the different schemes - besides
the merging of ppc and ppc64? 

Or how about the current status of both build architectures?  It seems
that people are fixing one build and breaking the other...  :(
