Thanks, maacruz. I think I'd tried that once before. On the N810 I get a bunch of package errors for dbus, dbus-1-utils, gconf2, libdbus-1-3, libgcon2-6, mini-rc, sysvinit, osso-pdf-viewer. Something is depending on older versions than are (or will be) installed. Maybe I'll poke around some more, but I'd rather not mess it up more.
