Jerky Mouse Movement

["Thomas H. George" <lists@tomgeorge.info>]

After a dist-upgrade from Sarge to testing and to a kernel built from 
linux-source-2.6.17 my mice - one old fashioned ball mouse and one Wacom 
Graphire mouse - only move in jumps and starts.    Clearly there is 
something wrong with my setup but I am having difficulty finding the 
fault.  I built the 2.6.17 with the same .config I used with a 2.6.11 
kernel and Sarge and both mice worked perfectly before the upgrade.

Any suggestions as to what I have missed would be most welcome.
