And one more grain of evidence... On a boot that makes it as far as the FreeBSD installer, if I hold down a key, qemu CPU usage seems to go up from about 2% to about 3%. It appears that at least qemu is not frozen and is processing keyboard input. I suspect this might provide a clue for someone who knows the internals. I also attached a picture of where the 11.1 install gets stuck.
