I like PowerArchitect.

It's open source and quite nice, but it does not support Firebird
directly.

To generate SQL it has a "Generic SQL-92" mode, but I don't know how
close that is to the Firebird SQL

the software is almost obsolet since CharonWare has been bought by
QUEST. I've tested TOAD Data modeller but it doesn't support firebird yet.
