Executing xinput only applies the change for as long as the device is still plugged in, so your KVM switch causing the settings to be lost isn't surprising (as it likely causes the device to be shown as disconnected).

You may want to read through http://www.x.org/wiki/Development/Documentation/PointerAcceleration/ as it covers various methods to improve the acceleration profile and speed using xset.  I have a script on my work system which I'll look up tomorrow and reply with which might help you out as well.  What operating system are you using?  Just curious.
