Note that predict() is a generic function (see
http://cran.r-project.org/doc/manuals/R-intro.html#Object-orientation). 
I don't think there is a method in geoR that does what you want.

The package gstat has a method for objects of class gstat (see ?gstat, 
?predict.gstat and the ASDAR book). You can coerce your variogram fit 
from geoR to the respective class used in package gstat with 
as.vgm.variomodel(). You can do kriging with krige.conv() from geoR too. 
But I think you have more options in gstat.

Tom
