UPDATE: The original poster had mistakenly said this was about W^X, it's not. It's about the NX bit, which is an emerging feature on newer AMD processors. This can allow for in-hardware per-page memory protection mechanisms. Intel is not yet rolling this feature out. OpenBSD's support for the NX bit is not yet available, but should be part of the amd64 support, which is being worked on.
