I put this in the discussion on kubuntu forums, but I'll put it here as well. I don't get notifications either on 9.10. What I've found is if there are updates waiting before a reboot, and then I reboot, I will eventually get a notification. If updates subsequently become available however, I won't get a notification until I reboot again.
