Thanks to all who helped me out on this one.  The general consensus is
that the ROM in the drive is responsible for this strange behavior.  My drive
contains the new ROM, which was supposed to fix the famous "sticky lubricant"
problem.  A side effect of this is random seeking during idle periods.
Unfortunately, mine seems a bit overzealous.

I'm going to try a remedy suggested by phaedrus@u.washington.edu:

If this doesn't work, I'm going to scream like hell at Apple and the
dealer (who did nothing about the problem when it was under warranty)
until I get some satisfaction.  The computer is only six months old.
