I am a career counselor in the US (dealing with resumes every day), and I use the word without the accents, partly because accents are not used in English (so using them looks affected), partly because it is too much trouble to get the computer to do them. But I'll bet the novelty spelling with one final accent got started because someone was trying to distinguish the word from "resume," as in "I will resume watching TV after I finish writing my resume." Doesn't make it write though! ; )
