NetBSD and OpenBSD share some history, and share some source code, but 
the kernels are not 1:1 compatible with each other.  There are too 
many changes to list.  The kernel interfaces vary from exactly the 
same, to slightly different, to completely and utterly different.

In OpenBSD, Interfaces attempt to be platform independent (little-endian 
scsi raid cards on macppc for example), and only things that are device 
specific are specific to each port (such as northbridges).

You should check out the OpenBSD web pages at http://openbsd.org as 
those describe the project goals and theories.

If you want to look at the actual interfaces, look at the man pages and 
source code.  If your system doesn't have those, they are online at 
 http://www.openbsd.org/cgi-bin/man.cgi and 
 http://www.openbsd.org/cgi-bin/cvsweb/ respectively.
