I am extremely surprised by your results, because the failure message you are showing shows that the Open Firmware implementation provided by qemu is incomplete, and as such is not able to fulfill the requirements of the OpenBSD kernel (except for installation media), and the failure ought to be the same regardless of the OpenBSD version being tested. So the root cause might be different, with something the OpenBSD kernel causing Open Firmware to clobber some of its own memory. Who knows. Since OpenBSD runs on real hardware, that's something for the qemu people to fix, there isn't much which can be done on the OpenBSD side of things.
