Johannes,

you do know the related environment variables

GRASS_MESSAGE_FORMAT
GRASS_VERBOSE

right?

Check <http://grass.osgeo.org/grass64/manuals/variables.html>.  Especially for 
the "VERBOSE" one, the manual states:

"This variable is automatically created by g.parser so that the --verbose or 
--quiet flags will be inherited by dependent modules as the script runs."

Best, Nikos
