John,
  I had the same problem after having a bad GURU.
  The only way I was able to fix the problem was to short the battery for
  a second. I did this by jumpering across the vcc and ground pins of the
  real time clock with the power turned off of course.  Only needs a second.
  The other way would be to completely disassemble your computer and remove
  the battery which is soldered in.  
  Somehow the real-time clock chip is being put in a strange state.  None of
  the software reset/load/save commands work when it is in this state.
  You will need to look at the schematics in your manual to find out which
  chip is the clock chip and which pins to short.  This shouldn't hurt any-
  thing because there is a resistor between the battery and the clock chip.
  I don't have my manual here at work so I can't tell you where things are.

  Good Luck,
   Alan
