Hi Stephan,

o.k. I didn't think of that. So another try:
Generate a .prj file for your data and generate a new
location with r.in.gdal which *should* accept this .prj file.
Here a sample for Gauss-Krueger (hope it is correct):

PROJECTION TRANSVERSE
UNITS METERS
DATUM POTSDAM
PARAMETERS 
1.000
9 0 0  
0 0 0  
3500000
0.0

Please tell me if this helps.

Markus
