Mouse moves one pixel, screen re-enabled

In the 8th of June a guy sent an email like this:

Hi all;

I may have found my screen blanker problem, my mouse, when laying there, moves 
about 1 pixel in a random direction every 30-45 seconds.

Its an rf mouse, logitek, talks through a usb dongle.  Frequency unk though.

Is there some way to reduce the sensitivity of the "mouse has moved" logic so 
that these little one pixel motions don't disable the screen blanker 
completely?
--------------------

People told him it was not possible. 

Well, I have a similar problem. Since it is impossible to tell X to
ignore erratic movements, is there at least a way to tell it to ignore
*all* mouse movements? There should be an option in Xorg.conf that made
Xorg calculate the idle time based solely on keyboard activity and mouse
button clicks, but not on mouse pointer movement. Ideally this would be
controllable with xset so I could write a script that enables it right
before locking the screen.

This is not only useful to people with wild mouses (like me and the
initial mailer). It is also useful for those situations in with someone
accidentally kicks the desk and the computer wakes up. It also seems
trivial to implement in Xorg (but please, don't ask me to send the
patch... The overhead of learning the internals of Xorg would probably
be enormous).

Is there a way?

Thank you.
