After looking at the @shadfc django ticket, I reimplemented the monkeypatch as follows:

from django.core.files.images import ImageFile
def _get_image_dimensions(self):
    if not hasattr(self, '_dimensions_cache'):
        if getattr(self.storage, 'IGNORE_IMAGE_DIMENSIONS', False):
            self._dimensions_cache = (0, 0)
        else:
            close = self.closed
            self.open()
            self._dimensions_cache = get_image_dimensions(self, close=close)
    return self._dimensions_cache
ImageFile._get_image_dimensions = _get_image_dimensions

To use it, just add a IGNORE_IMAGE_DIMENSIONS = True to your storage class and it will not be touched to get image dimensions. Likely:

from storages.backends.s3boto import S3BotoStorage
S3BotoStorage.IGNORE_IMAGE_DIMENSIONS = True

I still need to investigate where the numbers are used, to know if simple returning (0, 0) can lead to any problem, but no bug raised for now.
