Comment(by Richard.Kralovic):
I think the kernel driver works fine. My major concern is the way how
Xglamo handles movement events. I'll make some more tests if the kernel
modifications are necessary at all, maybe this is not the case. I am not
sure about how exactly the in-kernel evdev framework works, but if I
understood the source correctly, then at least the queue size in evdev.c
(EVENT_BUFFER_SIZE) needs to be larger. Otherwise, if there is a slow
client (such as Xglamo), some events (correctly reported by the neo
touchscreen driver) are forgotten due to queue overfull before Xglamo
actually reads them from /dev/input/eventX.
