good to have another archaeologist here. I think you should
look for some work done by Benjamin Ducke in the past few years.
I'm quite sure he built an XTENT modeling procedure for GRASS,
that he presented at CAA 2007 in Berlin.Should you find what you need, may I ask you to add a brief
summary on the "Quantitative Archaeology Wiki" at
http://wiki.iosa.it/ under the "Spatial Analysis" section?
It would be of great help to have such documentation collected
and easily retrievable for other researchers.
Also it would be nice to have something in the GRASS Wiki's Archeology page. There seem to be a number of archaeologists using GRASS but that page remains empty 
Papers presented, list of key modules, examples of field projects using GRASS, links to other projects of interest, that sort of thing. With that we hope to encourage GRASS/QGIS/GDAL micro-communities suited to the needs of each research field.

(people of other fields are welcomed to start their own pages there as well; create yourself an account and go!)
