I do have a script and series of patches which allows me to run almost all
OpenBSD ports in QEMU, see here: https://github.com/catap/obsd.sh

You need that script and qemu from ports where all required patches was
backported.

Some platforms needs alfo fixes for bios, and in my repo you can find
prebuild versions.

Keep in mind that Sparc64 is quite slow because need future work with bios
and qemu to allow more than one CPU. It is doable but I not sure when I do
have enough space in my head to do it.
