Two STONITH devices for one host, _both_ of which you expect to trigger, is nothing I remember as ever having been supported, up to this point. What you can do is to run staggered fencing, that is, a higher-priority fencing device fires first, and then _if that fails_, another lower-priority one does. However, in Pacemaker 1.1 this fallback to secondary STONITH devices (with staggered priorities) simply hasn't yet been implemented in stonith-ng. It's currently on the list for Fedora 17, and if I understood Andrew correctly that release should also cover your "both A and B must succeed for fencing to be considered successful" scenario. So perhaps you can be patient until then and settle for IPMI in the meantime?
