I installed the Feisty beta and was experiencing the same issue -- almost every time I resumed from sleep, my keyboard and mouse wouldn't work. I created the suspend and resume scripts myself and it completely fixed the problem. This is with my HP Compaq nw8440 laptop, so I suspect it's something endemic to HPs. Just adding another report of success with this fix.
