If you can have grub chain to OpenBSD's boot loader, you can set the port address with 'machine comaddr'. Yes, that is right. But it does not fix two other issues. First, you need I386_BUS_SPACE_MEM instead of I386_BUS_SPACE_IO. The console is memory mapped and not accessible via outb/inb. Second, registers need to be accessed in 4x space mode. Means, the register you want to access has to be multiplied by 4 before accessing it. All those issues are caused by the console being connected via PCI (puc(4)) as far as I can see.

Re: OpenBSD on Intel Galileo
I had the machine I worked on for this was some OpenBSD VM I purged some time ago. I was grepping through IRC logs and actually found a diff: #somewhere_20140227.log:[00:23:44] Bluerise This is my galileo workaround: http://gbpaste.org/CfG4P I’m glad I keep logs… Good luck!
