also, don't know if your mac has a PMU that you can reset.  check the
apple website for your model.  if the procedure is something you can
do on a machine that doesn't boot, then try that.  i have seen power
outages cause strange behaviors (especially if the PRAM battery was
dead or getting weak), and sometimes equally strange things were what
succeeded in resurrecting the computer.  things that didn't seem to
make sense on the surface.
