Hi Brian,
     Big Thanks~
     I see the releng direcctory, find th at the spec of ppc64 just support
BE ,and the bootloader is yaboot.  So I will use a new spec reference to
the ppc64 BE spec, modify the bootloader as grub ,arch type and use the
stage3 I have just compilied to build livecd. If I have more progress I
will put here .Thanks ~
