Back to the graphic run with 11.1...

If I let it sit a while, I see the following I/O warning which might 
explain the lack of keyboard response:

+ qemu-system-ppc64 -cdrom 
Save/FreeBSD-11.1-RELEASE-powerpc-powerpc64-disc1.iso -drive 
'file=freebsd-ppc.img,format=raw' -boot d
Fontconfig warning: "/usr/local/etc/fonts/local.conf", line 1093: saw 
number, expected matrix
main-loop: WARNING: I/O thread spun for 1000 iterations

qemu at this point is using very little cpu:
