Just to (not quite) wrap up this thread...
Someone reached out to me privately to provide some hardware that can run
Fedora aarch64, so once I receive that my immediate need should be
satisfied assuming the same problem is plaguing it and s390x which is an
assumption at this point.
I'll take a look at the IBM community stuff while I'm on holiday after this
week which may also be a stop gap.
Thanks,
Richard
