s.vol.rst - precip interpolation ?

I am looking into means of generating rainfall (raster) maps from
site data, and am aware of the basic methods of interpolation
supported by GRASS such as s.surf.idw and s.surf.tps (now
s.surf.rst I believe). What I really want however is to interpolate
using elevation as an independent variable. A suitable method is
that of Hutchinson, implemented in ANUSPLIN ( a commercial
package) using thin plate splines.
Does anyone know of a GRASS package or freely available code
which can do this ? I guess that s.vol.rst (referred to in the GRASS
web pages) would do the job, but has not yet been implemented.
Any info gratefully received, before I re-invent the wheel.
