That was indeed the problem. The solution was to switch a setting in the BIOS which enabled the com0 port. Duh! It was there from the beginning to see, but I didn't know certain OpenBSD terminology yet to understand how the different levels of access to the port were named and interact. E.g. what precisely "configured" (as in "Device not configured") referred to, namely that it's not me who had to do that configuring manually in whatever securelevel etc. of the fine OpenBSD software, but that it should have been the autoconf mecanism of the kernel which should have done it, so I searched around without realizing, what is now obvious to me, too, that the configuration had to take place -- manually indeed -- before OpenBSD even got it's chance to do it's own configuration. So, more RTFM cleared things up, and now I got a better grip on the system. This also enabled me to get gpio working on that and other boards. Great fun! Thanks to all who helped! Great software!
