Impossible to say.  You are dealing with bad hardware.
If this happens after closing the lid, likely you have an
ACPI problem.  ACPI is the system of sleeping/resuming
hardware on your laptop for suspending.  If I'm getting
what you wrote, your pointing devices would be gone.

If something causes a pointing device to change, it's
bad hardware.   I can't think of anything else.

Were I to disable the trackpad as suggested,
and then the T43 encountered whatever stimulus
causes the spontaneous switch from trackpoint

misoperation) or would the machine become
disabled because the trackpad would now be
disabled?

Good reason to disable the trackpad in the BIOS!

Happy Turkey!
