if it is just your APPLICATION that needs to not have motion events... then why don't u simply disable it listening to mouse motion events? (dependant on if its xlib, or you use a toolkit like qt/gtk etc.) you likely can get control over the eventmask of a window somehow and simply turn off motion events (and button motion events) in the mask. no need to hack a new version of x (quite problematic to ship) and no need to even modify the toolkit. you can probably do it entirely from the application.
