After spending the day visiting relatives, I came back to the notebook and
put something down nearby.  I then went away for a moment and upon
returning discovered the screen unblanked but the mouse not functioning. 
Flipping workspaces relieved my fear that 2.6.0-test2 had crashed, but
still no mouse.

So I decided to unplug and replug in the mouse (its USB after all).

This allowed the mouse to function again.

This is what was recorded in the message log:

I'm guessing this is where the USB Mouse was disconnected and reconnected
(there where no lines between these two sections, nor for several hours
before and after):

About 9 hours later it happened again, only I did not have to disconnect
the mouse for it to recover (in fact, I did not even know the situation
happened again until I looked in the log).
