And maybe the workaround in the OpenBSD code linked by Christos fixes this missing configuration.
I guess that BIOS is the responsible in my laptop. I reintroduce the proposal to the NetBSD development team: it would be great if this fix was applied to NetBSD code too. It is neither a quick, nor an easy work, but maybe some kernel experts can exactly know what to do.

Following your detailed report (thank you!) I tried to do the same, with no success: the "can't map mem space" error is still there about the device iwn0. My BIOS is apparently pretty simple and maybe the factory defaults were not so different from the actual configuration.

Ok, I remember it, seen in other machines, but in the laptop nothing similar is present, unfortunately.

If it can help, I ran NetBSD not only after a Linux boot, but also after a Windows 7 boot, and the error about the WiFi card was the same. Obviously, the card worked correctly both with Linux (Xubuntu 16.04) and Windows 7.
