The T61 has both a touchpad and a trackpoint.  Seems like on my T42, 
only one works.  Possibly there are settings for psm(4) or the synaptics 
touchpad driver is needed.

No, please stop recommending this.  Here's the whole story:

AEI is the wrong option.  If you want to stop xorg from using HAL to 
detect input devices, there are two good ways:

1. Set Option "AutoAddDevices" "Off"
2. Build xorg-server with the HAL option disabled.
