I spent a few hours trying to figure out how well this scheme could work for Ubuntu/Lucid. Things are in bad shape. Speakup basically is incompatible with PA on Lucid for now. The problems seem to come from multiple PA instances not sharing properly. If you switch-user to a new user on Karmic or Lucid, the new user has no access to the sound card. With the gdm PA instance running inorder to speak console login prompts, and the user PA running in Gnome, I can't get both to work at the same time. Since I'm not aware of any time that this has ever worked properly on Ubuntu with PA, I suspect it may be years before these issues are fixed.
