One other thing I forgot to mention: if you install MacsBugs onto your
ISO, you need to provide some mouse or keyboard input around the time
when the happy mac icon appears (I normally capture the mouse and move
it around a little), otherwise as you mention you see a freeze just
before "Debugger Installed" appears.

My guess is that MacsBugs is trying to work out whether to use ADB or
USB for keyboard, so unless the OS 9 ADB driver gets any input then it
can't decide and hangs on boot. Then again this could be another bug
somewhere in the QEMU ADB emulation...
