You have to download the ODF converter in RPM from Novell's page http://download.novell.com/SummaryFree. ... fdE4U58%7E and open it with File-roller(maybe you have to install the RPM package from Synaptic) and save it in any folder; in a terminal you have to write:
$ sudo cp usr/lib/ooo-2.0/program/OdfConverter /usr/lib/openoffice/program/
$ sudo cp usr/lib/ooo-2.0/share/registry/modules/org/openoffice/TypeDetection/Filter/MOOXFilter_cpp.xcu /usr/lib/openoffice/share/registry/modules/org/openoffice/TypeDetection/Filter/
$ sudo cp usr/lib/ooo-2.0/share/registry/modules/org/openoffice/TypeDetection/Types/MOOXTypeDetection.xcu /usr/lib/openoffice/share/registry/modules/org/openoffice/TypeDetection/Types/
And ready, you can open and save files in the Offie 2007 format.
