Wait, I think I'm missing something. You said that the hardware keeps context which cannot be exported, but how could we possibly use this for anything other than digest without creating trivial DoS problems? For example, if any user can start a hash process without finalising, then they could make the entire hash offload device unavailable for other users. If somehow your hardware contained multiple hash contexts to alleviate the problem, it could still be brought down easily by starting a large number of partial hash operations. So I cannot see how this could possibly work at all.
