Sorry for yet another repost, solution:

## Create internal tiles
gdal_translate -co TILED=YES old.tif new_tiled.tif

## cut out a chunk of an image, assigning appropriate georeferencing
## as always gdal uses top left and lower right corners of the image
gdal_translate -srcwin 0 0 2000 2000 in.tif out_0_0.tif
gdal_translate -srcwin 2000 0 2000 2000 in.tif out_1_0.tif
