You are aware, I suppose, that general purpose *nix system (such as *BSD an Linux) will never be a real RT without major changes.... So, the only thing you can get from it is modified scheduler and interrupt handling, but this buys you oonly so called "soft-RT"... As I understand, that's what the RTLinux project is about. And no, there is nothing exactly like this for BSDs, although you can find a couple of diffrent variations for scheduling algorithms.
