The problems aren't coming from tslib so I leave that to someone else.

Our raw data sucks so bad that even though we average it in the driver
over 32 samples before we publish it down the input device, the "tall"
axis averaged data still shows bad behaviour.  By the look of it
rejecting excursions alone in the driver should really help that 32-way
averaging to do its job, if it doesn't add excessive delay or
quantization of movement, so tslib massaging might not even be needed.
