Is it a violation to list an alternate airport based on an approach your aircraft is not equipped to execute?
I have not found any LOI's that cover this specifically but a broad interpretation of 


  § 91.205 Powered civil aircraft with standard category U.S. airworthiness certificates: Instrument and equipment
  requirements. 
  
  ...
  
  (d)Instrument flight rules. For IFR flight, the following instruments
  and equipment are required:
  
  ...
  
  (2) Two-way radio communication and navigation equipment suitable for
  the route to be flown.


Once can broadly say that if you intend to fly an ILS (alternate or not) 91.205 requires suitable equipment i.e. an ILS receiver and CDI capable of displaying as such.
