As another follow up, it appears that the root problem is
hardware-related.  I started seeing the same symptoms again a little
while ago and they've pretty much disappeared since I turned off the
trackpad (I only ever use the trackpoint, so it's no loss for me).  I
suspect that I may have left a connection loose last time I opened my
notebook but haven't had a chance to open it back up and check.
