I experienced some problems with the synaptics touchpad on a really old laptop with linux-2.6.0-test4, where movement detected by the touchpad would cause a stream of kernel messages to be logged.
I'll test again with test5. I doubt this is related to recent changes with the posting events to the random pool on key and not mouse movement.
