Is there any error messages in the server log?

The only 2PC related change in 8.4 that I can recall is that we changed
the default max_prepared_transactions setting from 5 to 0. Perhaps you
forgot to set that? See
http://www.postgresql.org/docs/8.4/interactive/runtime-config-resource.html#GUC-MAX-PREPARED-TRANSACTIONS
for more information on that parameter.
