With the definition of displacement mapping i gave it is.

But of course the question 'does POV-Ray support displacement mapping' 
does not make much sense for various reasons (in fact nearly all 'does 
POV-Ray support xxx' questions do not make sense).  And to be fair the 
posting that started this thread also did not ask this.  An internal 

 
limited value.  What would be interesting is support for adaptive render 

time subdivision of meshes with displacement.
