Nah, the .xscreensaver file is the correct place for flags and configs as read by the full xscreensaver process when it executes xscreensaver delivered hacks. Hacks are self contained binaries that display different animations to the X desktop and are individually coded with flags and arguments just like any other Linux binary. Currently on Maemo5, the xscreensaver package just seems to dump a bunch of these hacks into a directory where the Live-Wallpaper process can access them. They then execute with the default flags and arguments. Perhaps I could find a .livewallpaper that could do the same thing.... Of course, finding where the xscreensaver.deb file dumps the hacks onto the N900 would help in testing what flags and arguments are accepted by running them individually.
