Hello again Mark, Some progress here.
You were right about the USB trouble. Instead of a USB key I tried to put a sata disk on a USB tray and ran your image, but it failed too. same as before no fs0: available. Then I too the drive out of the usb tray and put it on one of the sata plug on the macchiatobin, booted again and, voila ! This time I got the OpenBSD prompt right. here is the log for the record.
