Based on the information provided so far, if I were to start working
on ppc for OS X now, I'd start with ppc-aix-port. Zero while functional,
was extreemly slow. Native support would be best.

Looking at this tree:

http://hg.openjdk.java.net/ppc-aix-port/jdk7u/

I see that it is following jdk7u and has tags for jdk7u14 so it has
MacOS x86 support that was merged in around 7u6. 

The hardest part of the work will be in taking the code here:

hotspot/src/os_cpu/aix_ppc/vm/
and porting it to
hotspot/src/os_cpu/bsd_ppc/vm/
