I was wrong (already admitted that in another email on this thread).  
But PPC was never supported as fully 64-bits.  Well you could write 
64-bit user applications but all of the runtime was still 32-bits.  You 
had to carefully craft your application to have a 64-bit (basically 
standalone) piece and everything else that interacted with the OS as 
32-bits.  The X86 version of Leopard didn't have that problem.
