Ok, based on this latest information I'm going to mark this bug as "invalid" because the patch added as part of the SRU should be making things more correct, and the difference appears to be handled appropriately by modifying the acceleration scheme parameters.
I will also note that the acceleration and sensitivity is greatly affected by the precision of the mouse, and that the X input handling is not automatically scaled to take this into account. For example, the default acceleration and sensitivity is too high on a high precision mouse like the Apple Magic Mouse, while it is perfectly reasonable for other mice. Please feel free to reopen the bug report if you believe this is not the appropriate outcome.
