I understand your concerns, but this will make this feature useless for the
8 tablet models I was aiming it at. Most of them have 2000 LPI resolution.

The thing is, I suspect, there is basicly very little to none real devices
correctly specifying their resolution in the report descriptors. Plus almost
no one uses the resolution field in input_absinfo currently and especially
for generic processing (as opposed to working with a specific device). Even
more, I have failed to find any noticeable amount of device drivers filling
it in, but it could be my fault of course.

So, I think, now is the best time to standardize on this and do real
changes.
