when using two button scrolling, the drivers often send lots of
scrolldown event when i release the finger quickly. which is very inconvenient
when trying to scroll up
i monitored the scrolldown event with xev and 
the number of scrolldown * VertScrollDelta = 5855 - the end position.

i downloaded the debian sources and hacked something like :
if (x == 1 and y == 5855) { w=z=0; }
and the problem disapeared. but that's dirty.
looking at the source i can't find the problem through
