I've just reflashed my N810 and wanted to reinstall pygtkeditor, but didn't want to have the python-pygtksourceview package permanently shown in the update list of package manager. So I created a dummy installer for libxml2juuiiii using pypackager that has libxml2 as a dependency. The package is very small as it only contains a text file with a short line of text.

With this installed the other missing dependencies (flash-and-reboot, etc) vanish and pygtkeditor can be installed solely from within application manager.

I've only tried it on the one tablet. Hopefully it will work for you.
