The last working ISO I tried was probably from July (definitely no 
earlier at least) if that helps slightly. Unfortunately, I deleted my 
older ISO's.

Unfortunately, I don't see any older 12-CURRENT images archived to try 
and get some idea of when this broke.

If I have some time, I'll see if it's possible/feasible for me to build 
a PPC64 image of some kind from a PC to try unless someone has a better 
idea of course. :D

Thanks!
