OK, I should not complain to loud -- indeed I moved the mouse pointer
fast...

I have just added a time output to the Nimrod program:

echo round(event.x), " ", round(event.y), ":", event.time 

stefan AMD64X2 ~/fups $ ./test 
3 461:32626589
54 459:32626605
99 459:32626617
144 459:32626628
183 466:32626640
232 468:32626652
281 468:32626664
344 468:32626676
393 468:32626689

So we get an event every 12 ms -- more makes no sense for a 60 Hz TFT
display.
