Good sleuthing, Dan.  In my case the Startup CDEV was set correctly to an
internal HD40, but an external HD80 still carried a Finder Startup file left
over from the days when it had its own System.  Trashing the superfluous
file cured the keyboard problem.  Although the file must have been on the
HD80 for a long time, it does appear that the problem only manifested itself
when the HD40 System Software was updated to 6.0.5.
