Check for devices with abs X/Y, no rel X/Y and > BTN_LEFT? Or do you have other crazy devices doing that as well? i'm pretty sure that for any combination of axes you can think of, there will be a device out there that has them. but yes, this keyboard in particular was the first of many to cause the rel/abs handling in evdev. If it helps, my other Microsft keyboard has REL_HWHEEL and a bunch of ABS_ axes (including some multi-touch axes, but I'm not sure typing really counts as MT interaction). the amendment to your patch wouldn't be hard, you'd just have to make sure that devices that don't have buttons don't get labelled as touchscreens and we get your device supported while maintaining the previous behaviour for all other devices.
