Thanks. That is how I test. I guess that it is enough so I no longer wish
to use /dev/input/eventXX directly for testing.

Sure. Let's try.

It seems there are a few tests tslib. Why should we duplicate them? Tslib can
read from /dev/inputXX...
We are making parts of tslib optional for us, not all of it obsolete
for everyone ...

It seems more like a restriction than a goal. I really agree that we
should get code
upstream. We also have to make things work :-) What shall we try first?
We are in a paradox, I know. We need something that works, and then we
try to put
If upstream does not like the filters we'll find out what to do... I
guess they will
say why, and that we will try to solve the issues.
