It's fixed in 2.0.1, see the topmost entry in WhatsNew in cvs.

There is another improvement there for IBO - from the 2.0.1 release notes:
"
(CORE-1012) Since Firebird 1.5.3, neither the relation name nor the
alias was being returned for columns participating in a GROUP BY
aggregation with joins. This problem was reported to affect
particularly applications using IB Objects, which maintains internal
structures to support "live" searching of tables underlying joined
and aggregated sets. Fixed by A. dos Santos Fernandes.
