 your problem?  Reading your logs, it seems a little different.

 using  the glide sensor in relative mode.

 No, my problem is different from the video.  In the X axis, the cursor
 jumps around (as my kmsg snippets show) while in the Y it is smooth.  It
 does jump around in the X somewhat predictably, getting more erratic
 toward the sides, I think, and sometimes being almost usable.  Here's the
 tail end of Xorg.0.log, 'not sure about relative mode, can you tell from
 this?
