wow that worked. :)

i've set my mouse to /dev/ums0 and set Option "AllowEmptyInput" "off", because
without that line i couldn't use the mouse.

even with very fast movements i don't get any random clicks anymore. although
this a solution works for X, for the console the only way to use a mouse is
moused(8).

cheers.
