The latest development version of MATPOWER has some utilities for finding islands and I have happy to send you the relevant functions off-list if you like. MATPOWER should handle a DC OPF with a system with islands just fine as long as each island has its own reference bus and each island has a feasible solution (e.g. sufficient generation to meet load without overloading lines).
