You can stop hildon-home with the command (run as root) which may save a bit of memory. And can stop it starting at boot by editing the file and commenting out the line (in this case that means put a # at the beggining of the line)However you still get the desktop views (just without any widgets or shortcuts) as that seems to be provided as part of hildon-desktop, and should you go to edit the desktop and click on the desktop menu, then hildon-home will automatically be (re)loaded.
