Used to have this myself.
Solution seems (in that doing this solved it AFAICS) to be putting the 
SWCursor line in your X config file.

Here's my compete section -

Section "Device"
        Identifier      "Trident Cyberblade 7i"
        Driver          "trident"
        Option          "SWCursor" "on"
EndSection

HTH,
