I've been out of the loop for a while since my Google SoC project, so  
I don't know how relevant this is, but I did manage to netboot a dual- 
processor single-core G5 into single user mode under its own console  
after modifying Sanjay Lal's original code; I also had a friend  
successfully boot a dual-core Power Mac G5 with the same kernel. The  
patches (though now two years old) are available at http://netbsd-soc.cvs.sourceforge.net/viewvc/netbsd-soc/ppcg5 
. I doubt that this code has been integrated into the official  
sources, so it might be of some use to you now.
