Thanks.  I don't have a mouse section in my xorg.conf so I used the 
kernel parameter.  I don't think this is a placebo effect: it seems 
setting the poll rate to 250 helps more in X.Org than it does in 
Windows, especially when grabbing a window and moving it; it seems much 
less "jerky" now and up to par with Windows.
