Mark,
	I believe r.stats only deals with square meters or cell counts.
According to our on-line manual:

DESCRIPTION
     r.stats calculates the area present in each of the
     categories of user-selected raster map layer(s).  Area
     statistics are given in units of square meters and/or cell
     counts......<stuff deleted>

So I think awk, as you mentioned in your original posting, may be the way
to go, but I'm sure there are other methods of determining acreage. It could
be done with r.mapcalc........plus others.

Have a Great Day,
