The list of functions that are supported for polyhedral surface
geometries are documented for PostGIS 2.2 here:
So, for instance, try replacing ST_Intersects with ST_3DIntersects,
and your example should work.
Many of the functions were written before curve support, which is why
you may see a generic-looking "unknown geometry type" error.
