quick follow up.  tweaking activerecord/base.rb to

   def __instantiate(record)

and activerecord/callbacks.rb to

   def instantiate_without_callbacks(record)��
     __instantiate(record)
   end
   def instantiate(record)
     instantiate_with_callbacks(record)
   end
   def instantiate_with_callbacks(record)
     object = instantiate_without_callbacks(record)

while deleting the aliases works - so the issue is defintely in alias_methods
or rails' use of it.
