gdalwarp your input not defining the -tr (output resolution). gdalwarp
should be able to estimate a resonable res. Maybe try -tps if your input is
particulary huge. Then r.proj with the same res and compare which output you 
like best.

That would be very handy if r.proj could estimate the best output resolution
as well. I remember there was some discussion about completely replacing
r.proj warper with gdal warper. Any news?
