I uploaded the armel deb compiled packages to maemo garage: http://garage.maemo.org/projects/python-gtkhtml2/
It needs first libgail, libgail-common and libgtkhtml2. These packages can't be installed with Aplication Manager.

Soon I will upload all packages to extras-devel repository.
And source code for gnome-python-extras (renamed to python-gtkhtml2). I only modified the debian directory for compile only the gtkhtml2 module. A bit rude but it worked.
