If you attribute your grid boxes, then the areas will be rasterized by
v.to.rast with the assigned values.  This can be done in v.digit
on a manual basis.  Alternatively, since it is a standard grid of some
sort, you could likely create a dig_att file either manually or via a
script, etc. since the area attributes would be a standard distance 
apart in either direction.  

Once the dig_att file is created, you would need to run v.support in order
for grass to recognize the attachment of the attributes to the areas, then
v.to.rast.
