Comment (by kuszinger):

 Got it!

 * Go to NC in Grass7.1
 * {{{g.region raster=elevation at PERMANENT }}}
 * {{{r.random -z --overwrite input=elevation at PERMANENT npoints=100000
 raster=elev_sparse}}}
 * {{{r.surf.idw --overwrite input=elev_sparse at user1 output=elev_sparse_idw
 npoints=7}}}

 Result is not interpolated.

 Also tested in the same mapset with Grass6.4
 * {{{r.surf.idw --overwrite input=elev_sparse at user1
 output=elev_sparse_idw_64 npoints=7}}}

 Result is ok in 6.4
