I did find out that hal was not running, so I started it, unplugged the
keyboard and mouse again and plugged them back in to no avail.  However, I
noticed that even though hal is now running, not all of the same services
are running on this system as on a similar system still at 5.7.

Oh, one more question: are you running at runlevel 3 or 5?
