(Get the code!)
I'm really puzzled by this. I'm using the same machine, with the exact same touchpad based on the USB id, and I don't see anything like this. The bcm5974 driver in precise is identical to the one in 3.2, aside from the patch that Chase mentioned that wasn't present prior to 3.2.0-17.26. It's hard to imagine what might be causing the difference in behavior.
The logs show that even when the touchpad isn't fully functioning that it's being correctly detected, that the driver is being loaded, and that X is using the synaptics driver to support it. The driver never sends relative motion events, so the fact that it works at all suggests that the absolute coordinate events are being sent from the kernel driver.
Chase, given the above, can you provide any insight on what the driver could be doing that could be resulting in the behavior that Clint is seeing? On the surface everything looks okay, yet there's obviously some problem here that I'm at a loss to explain.
