Most probably, yes.

There are not many people with this scanner out there and as far as I
know you are the first one using OpenBSD trying it :-)

Does the access to i/o ports work in OpenBSD like in FreeBSD?

Looks fine.

Most probably not necessary. If you really have firmware 2.0, you
should give your scanner to a museum because it's that seldom :-)

Looks like this code in sanei_ab306_get_io_privilege fails:

      if (dev_io_fd == 0)
      	 dev_io_fd = open ("/dev/io", O_RDONLY);

Maybe there is no /dev/io in OpenBSD or its name is different?
