On Thinkpads, the Trackpoint and the PS/2 mouse port share data lines.
The Trackpoint uses the PS/2 protocol. Having 2 mice using 2 different
protocols on the same data lines just doesn't work very well under X.
I think you'll have to set the protocol to PS/2, disable the Trackpoint
and just use the mouse, or buy yourself a USB mouse.

This may be another X architectural problem. XFree86 may only scan for
devices when it starts up; if a device is missing then, it's not scanned
for again. ISTR changing my XF86Config around so it had an entry for a
USB mouse, restarting X without a USB mouse plugged in, and plugging a
USB mouse in later and having it work though. This was on a Gentoo
machine with X 4.3.0, though--upgrade your X if you're using anything
older than that and try it again.
