Have to say that installing original deb didn't go smoothly for me as all python-pyside dependencies had to be 1.0.2 rather than 1.0.7 that apt-get install wanted to push. Just for interest I required the following:
libpyside1.0_1.0.2-1maemo1+0m6_armel.deb
libshiboken1.0_1.0.2-1maemo1+0m6_armel.deb
python-gconf_2.28.1-1maemo1+0m6_armel.deb
python-pyside_1.0.2-1maemo1+0m6_all.deb
python-pyside.phonon_1.0.2-1maemo1+0m6_armel.deb
python-pyside.qtcore_1.0.2-1maemo1+0m6_armel.deb
