For general kernel code, The Design and Implementation of the 4.4BSD Operating System, and for network/driver code, Stevens TCP/IP Illustrated Volume 2 is a really good choice. Even if it doesn't match 100%, when you "get" those books and how code is/was written, it will be far easier to get into the OpenBSD codebase. -- May the most significant bit of your life be positive.
