Well, for powerpc64,  . . .

A) Using kern.vty=vt booted the 2-socket/1-cores-each G5 just fine.

B) Using kern.vty=sc stopped after the "Kernel entry at . . ." message.
   (This behavior with sc is not new, it is very old in fact.)

(The iMac G3 boots with sc and fails to do so with vt: blank
screen very early on.)

These are as of:
