Hi Derry,
My father in law has done both - drilled the hole to drain and eventually 
filled with
cement. He scraped out all rotting or moist wood first and also capped it 
with sheet
metal to keep out additional moisture. It has been about ten years since and 
the tree
appears fine. I personally feel that depending on the extent of damage, age 
of tree,
etc., if the hole is drilled and the inside kept from further rotting, the 
tree should
be fine as long as the actively growing tissues can stay healthy. Cement can 
be useful
for adding strength to an otherwise weakened trunk.
