In OpenBSD you get a console log by default, and, assuming you're starting X by the preferred xenodm display manager, you have a line in /etc/X11/xenodm/Xsetup_0 about the console, which you can comment out. Is it possible that you're using a display manager that does the same thing? I've used openbox for years on FreeBSD and never had those errors, so I'm guessing at what might cause the console log one. I have no idea about the other one. Hopefully, someone with more knowledge will also answer.
