You can build one from:

git clone -b q800-dev https://github.com/vivier/qemu-m68k.git

./configure --target-list=m68k-softmmu

./m68k-softmmu/qemu-system-m68k -M q800 \
    -serial none -serial mon:stdio -m 1000M \
    -drive file=./virtm68k-etch.qcow2,format=qcow2 -net
nic,model=dp83932,addr=09:00:07:12:34:57 \
    -net bridge,helper=/usr/libexec/qemu-bridge-helper,br=virbr0 \
    -append "root=/dev/sda2 rw console=ttyS0 console=tty" \
    -kernel vmlinux-4.8.0-2-m68k \
    -initrd initrd.img-4.8.0-2-m68k \

With a 4.8.0-2, I've got:

[    0.180000] NuBus: Scanning NuBus slots.
[    0.180000] Now probing slot 9 at f9ffffff
[    0.180000] Slot 9:

Slot 9 is the graphic card:

(qemu) info qtree
bus: main-system-bus
  type System
  dev: mac-nubus-bridge, id ""
    mmio 0000000060000000/0000000090000000
    mmio 00000000f0000000/000000000f000000
    bus: nubus-bus.0
      type nubus-bus
      dev: nubus-macfb, id ""
        width = 800 (0x320)
        height = 600 (0x258)
        depth = 16 (0x10)
...

This can be a bad Nubus emulation in qemu.

Thanks,
Laurent
