Buy a USB hub?  Use the Thinkpad's keyboard, unless you have a pressing 
need for the numeric keypad on a regular keyboard?

The Trackpoint and the PS/2 mouse port share data lines on Thinkpads.  
The Trackpoint uses the PS/2 protocol, while most wheelmice use the 
IMPS/2 protocol.  If you have 2 devices that speak different protocols 
sharing the same data lines, it's highly likely that neither one will 
work.  One thing that will work is to disable the Trackpoint using the 
BIOS Setup or ntpctl, then make sure the mouse protocol for the PS/2 
port in your /etc/X11/XF86Config is set to "IMPS/2" and the Option 
"ZAxisMapping" "4 5" line is present for your mouse.

 see myself as outside."  At that moment, the Buddha was enlightened.
