So I thought it may not be a good idea to either make the two separate components interdependent, or make maintenance more difficult by copying a big block of code from one to the other.  Could resolve this by having the setup for the random saver (and that one saver only) be a special case internally managed by the kcmodule, then the same code could be used to generate both lists.

Yes, that would be my preferred way of doing it.  Means that the random saver is a special case, but then it is already.  Also some UI gets moved from krandom.kss back to the kcmodule, but it's only 2 checkboxes.

The state of these is saved to the random saver's config file.  This selection is in addition to the two options within the saver's setup dialogue, so if for example "Use OpenGL screen savers" is not checked than any OpenGL savers will be ignored even if their boxes are checked in the tree view.
