mouse sample rate

[Michael Soulier <msoulier@storm.ca>]

	Hey guys. Ok, a clip from my XF86Config file.

Section "Pointer"
   Protocol        "PS/2"
   Device          "/dev/psaux"
   SampleRate      45
   Resolution      100
   Buttons         3
EndSection

	I assume that by changing the sample rate, I can make the mouse
pointer move faster, increasing sensitivity of the mouse. But, is there a
way to make this take effect immediately, without shutting down X and
restarting it?
	KDE and Gnome allow you to do this, and I'm wondering how they
work. Do they intercept the mouse perhaps and not use this mechanism
directly?

	Mike
