Comment 19 for bug 188787

As I recall, KDE/Qt has a viciously hard time dealing with tablet devices listed in Xorg but not physically present. Enough that several developers have blamed tablet users for making it impossible to debug KDE and calling the addition a move by idiots. Timo may be correct that it also affects some usability tools.

Like I said before, what's needed to fix this is either a post-inst script to modify xorg.conf or a patch to wacom tools to support autoprobing / configuration. Re-adding the entries by default simply breaks someone else's use case.
