That seems to be correct. The python-qt4-sql package depends on qt4-sql,
and the information page at

  http://packages.ubuntu.com/gutsy/libs/libqt4-sql

says this:

  It includes support for PostgreSQL, MySQL, and SQLite databases. If you
  wish to to use the SQL module for development, you should install the
  libqt4-dev package.

It looks like you'll have to build the Interbase SQL plugin yourself. This
page should give you some basic information about building the Interbase SQL
plugins for Qt:

  http://doc.trolltech.com/4.3/sql-driver.html#qibase-for-borland-interbase

You'll need to get the source for the version of Qt you are using. You
should be able to get this by typing the following at the command line:

  apt-get source libqt4-dev

You shouldn't need to do more than just compile a couple of files, and the
document tells you exactly what to do. Let us know how you get on.

I believe QPSQL is the one you want.
