yes, r.in.gdal can dump raster attribute tables as csv files. Moreover,
information in raster attribute tables is automatically imported as long as
the field definitions contain information about how to use a field, e.g.
for color information or for labels.

I don't think db.in.ogr can read raster attribute tables: raster attribute
tables are not equivalent to vector attribute tables.
