I fixed this problem on a Socket7 motherboard with a SIS chipset by
changing from hardware cursor to software cursor.

In the /etc/X11/XF86Config* file, look for 

Section "Device"
...
        Driver          "trident"
...
EndSection

and try adding 
 Option "SWCursor" "true"
inside the Section...EndSection bit.

cheers, Rich.
