Different UTM zones are different coordinate systems. If you want to 
uses data form two different UTM zones you need to reproject them into a 
common coordinate system first. Finding such a system is up to you.

Reprojection can be accomplished with gdalwarp. If you need to do it in 
GRASS there is r.proj.
