Hmm..I added this flag to the psm device, but since the problem is pretty random, i'll have to see if it works. And in response to Ben Scott's email about strange actions by the mouse, I've had almost the same problems. My mouse moves horizontially back and forth for a few seconds at random times...its pretty amusing.
