Thanks Peter.  I got the emulate wheel working again with this:

$cat /etc/X11/xorg.conf.d/10-trackball.conf

Section "InputClass"
         Identifier "pointer"
         MatchProduct "ImExPS"
         Driver "evdev"
         Option "AutoServerLayout" "on"
         Option "Emulate3Buttons" "on"
         Option "EmulateWheel" "on"
         Option "EmulateWheelButton" "8"

Even though the mouse works normally, these lines at the end of Xorg.log make
me suspect that something is still not right:

[  5223.204] (II) config/udev: Adding input device ImExPS/2 Logitech Explorer Mouse (/dev/input/mouse0)
[  5223.204] (**) ImExPS/2 Logitech Explorer Mouse: Applying InputClass "pointer"
[  5223.204] (**) ImExPS/2 Logitech Explorer Mouse: always reports core events
[  5223.204] (**) ImExPS/2 Logitech Explorer Mouse: Device: "/dev/input/mouse0"
[  5223.204] (EE) ioctl EVIOCGNAME failed: Inappropriate ioctl for device
[  5223.204] (II) UnloadModule: "evdev"
[  5223.204] (EE) PreInit returned NULL for "ImExPS/2 Logitech Explorer Mouse"

Are those errors something to worry about?
