According to "qemu-system-ppc -M ?", g3beige is still the default.  The mac99 
machine is the default for ppc64.  (Are there newworlds that run a 32 bit ppc 
instead of a 64 bit ppc?)

I intend to get a mac99 kernel configured for ppc64, but haven't gotten around 
to adding that target yet.  I'm currently working on adding mips64.
