openbsd does have loadable kernel modules http://www.openbsd.org/cgi-bin/man.cgi?query=lkm http://www.openbsd.org/cgi-bin/man.cgi?query=lkm LD_PRELOAD and friends are also ignored on linux for setuid/setgid binaries, otherwise privilege escalation would be trivial, just start any dynamicly linked setuid binary with LD_PRELOAD and go to town.

OpenBSD's kernel modules are for development only. They require a securelevel change and a reboot to enable.
