I could not have your tweak to work on my own laptop. I had to change it this
way so that it matches:

+libinput:name:*CyPS/2 Cypress Trackpad:dmi:*svnDell*:pnXPSL322X*
+ LIBINPUT_ATTR_PRESSURE_RANGE=30:20
+ LIBINPUT_ATTR_PALM_PRESSURE_THRESHOLD=254
+
 ##########################################
 # Elantech
 ##########################################
 (only removed the "DellSystem" substring in :pn....)

Maybe the dmi id was changed in my bios (latest A10 IIRC) 

cat /sys/class/dmi/id/modalias
dmi:bvnDellInc.:bvrA10:bd08/28/2013:svnDellInc.:pnXPSL322X:pvr:rvnDellInc.:rn0PJHXN:rvrA00:cvnDellInc.:ct8:cvr0.1:

  Maybe :pn*XPS*L322X* would be wide & precise enough if Dell guys change this
in a new bios release, e.g. DellSystemXPS[13]L322X.
Or lighter :pn*L322X*
