I have tried the following code:

osg::Texture::Extensions * ext = osg::Texture::getExtensions (
state->getContextID (), true );
ext->glCompressedTexSubImage2D ( GL_TEXTURE_2D, 0, 0, 0, 128, 128,
GL_COMPRESSED_RGBA_S3TC_DXT5_EXT, page->Tile->BufferSize, page->Tile->LoadTile ()
);
The LoadTile method returns a valid pointer to valid data. I have tested that
previously.
This does not update the texture. It remains (aparently) unchanged in the
render.
In your code problem maybe what you have not allocated texture object.
Could you please show how you initialize _phisycalTexture?
I think usgin subload callback would be better in your case.
Mikhail.
