With GRASS 6.3 (not yet officially released but snapshots are available)
you can elaborate 3D data and export to KML.

For example, you can take a 3D drawing (DXF), import with v.in.dxf,
geocode with v.transform and export to KML with v.out.ogr as 3D
object. Note that the KML support in OGR is still somewhat limited but
I managed to export 3D buildings.

Additionally, if needed:
- reproject to LatLong with v.proj
- extrude 2D building footprints to 3D blocks with v.extrude
- drape 2D vectors over DEM with v.drape

Not really helpful maybe, but giving an idea,
Markus

PS: Works on MS-Windows/MacOSX, too :)
