I don't know how FreeBSD performs WRT realtime, but we used QNX (it's for intel) a lot at my last job. QNX's main thing is realtime support and the api looks like POSIX for the most part so if your applications are written carefully, they could run on BSD or QNX. It's even starting to get very stable with late releases (early versions were a little flakey). brad@pht.com
