Are you sure?  What does r.info say about the imported map?  Out of the top of 
my head, I don't think that the current region settings affect a maps extent 
and resolution while importing.  They shouldn't.

I guess there is no need to do so.

r.proj is another beast -- there you can either depend on the current region 
settings (in the Location/Mapset where you are reprojecting raster data to) or 
use the "res=" parameter provided by the r.proj module.
