Before I really get kicked: I don't think those refences are in the config, but there certainly are references to i386 diskless booting in some older online docs, like this one:
http://www.onlamp.com/pub/a/bsd/2004/04/29/Big_Scary_Daemons.html I tried something similar, because I wanted to see if I could mount an NFS partition from my Soekris, running OpenBSD, but I couldn't get it to work. I also couldn't get NFS support to compile properly, so I left it and dived into the "miniroot" stuff. This can serve as an alternative to mount / on NFS, except that it has quite stringent size limitations. By the way, the fact that PXE booting is also often referred to as "diskless booting" (which technically it is), doesn't make life easier for someone who is new to both topics, as they are both quite different. Finally, from the document above: "OpenBSD provides a kernel configuration specifically for i386 diskless operations. It's called DISKLESS." That config presumably contained all support that's needed for a Sun-style diskless boot, but it seems to have been obsoleted for i386. And from diskless(8): "The procedures for AMD64 and i386 clients vary somewhat to the stages detailed above. See pxeboot(8) for more detailed information." They seem to vary more than "somewhat"..
