The UI should know the difference as it should guide/force the user -
especially the less experienced ones which aren't expected to know every
bit of hardware and kernel-internal stuff (as in "do I need gzip
compression?").

And there are two (IMHO very) different semantics:
- select: enables/activates/includes necessary other parts (like the
  "gzip compression" example from above and other library-like).
- depends on: to purposely disable knobs because it makes no sense to
  configure e.g. ext-specific stuff if I don't have/want ext or because
  the physical hardware is not present/available (find more and better
  in Al Viros mail of course).
