I can only speculate that you are really referring to "s.vol.idw" (?) As the name implies, this is a module that uses the now outdated "site" data model for its input data. Some of those modules never made the transition to GRASS 6 and its new vector engine. It was still around in GRASS 5.3. They are generally easy to convert to the new API though.
But perhaps someone on this list knows more about it? It would certainly be useful to have IDW in voxel space. IDW is primitive and generally does not give results as good as spline-based interpolation (unless your data is very dense and regularly spaced), but it has the advantage of being simple (so it's easy to make sense of the result data) and fast.
