Wacom causes erratic mouse cursor movement

When you hold the Wacom pen in one position, you'll notice that the mouse cursor erratically moves a couple of pixels around one spot. In BeOS, Ubuntu and Windows this movement is a lot less, if not non-existent.
Unfortunately this filter doesn't fix the erratic movements completely, so I decided to compare the 'raw' tablet data:
- x-movement (BeOS on the left, Haiku on the right):
- y-movement (BeOS on the left, Haiku on the right):
The horizontal gridlines represent the pixel-boundaries on my monitor.
You can see that the 'raw' movement is a lot bigger in Haiku than in BeOS, but I have no idea where the cause of this difference lies.
Also note the difference in the time between two samples, between BeOS (left) and Haiku (right):
Although this could have been caused by the different methods used to capture the data: to a file in BeOS, to the serial port in Haiku.
