Not as in QGIS, but you can use eg. r.mapcalc to create a version of
your original raster at a reduced resolution. Other folks can give you
more guiding about using the recent Glynn's aggregation module in GRASS
6.3 (search recent dev & user archives for 'aggregate'). Take a look at
r.resamp* modules too.

I don't think this is possible now.
