I've got exact the same problem on my Dell Studio 15(58), first I thought resuming failed, but it seems that I just was impatient. Very annoying and always happens on the worst moments. It does not happen always though. one out of five times or so.
I had the same in Lucid, but then due some problems with fglrx I had some colored blocks on my screen to say that it was indeed resuming.
