Sorry if this is a stupid question.. but could someone please give a brief description of the difference between the ppc and powerpc branches? Spent a fair amount of time (not enough?) digging around but couldn't really find a clear answer...

Very easy: ppc was the old name for the now discontinued 32-bit
PowerPC architecture, powerpc is the name for the merged 32 and
64 bit PowerPC architectures.
All recent kernel versions only have powerpc, and no active
development had gone into the ppc tree for a few years before.
The only reason for keeping ppc around was that some platforms
had not yet been ported to powerpc.
