Hi Joel,
Previous e-mail, with kernel options still yields
/var./log/XFree86.o.log mouse error messages,
not as many: i got 2 in 4 hrs, of heavy use. I returned to original
kernel file and modified /etc/X11/
XF86Config file:
Section "InputDevice"

# Identifier and driver

    Identifier  "Mouse1"
    Driver      "mouse"
    Option "Protocol"    "wsmouse"
    Option "Device"      "/dev/wsmouse"
    Option "ZAxisMapping"  "4 5"

EndSection
