Actually - we've pretty much got this in 7.1 anyway.
Plpgsql gives us EXECUTE <text> so we can generate triggers etc on the fly.
\i lets us parse a file
So - you could:
-- import functions from module
\i auto_timestamp.pgmod
-- add the triggers
auto_timestamp_addto(mytable,mycolumn)
-- remove the functions provided by the module
auto_timestamp_remove_module()
Does this make sense, or am I talking rubbish here?
