I've tried your patch (+some minor fixes to make it work) but running texdepth with it results in failing assertion rb->Format == MESA_FORMAT_X8_Z24 (s_readpix.c:123). I've also tried modifying span functions to convert between Z24_S8 (hw format) to S8_Z24 (mesa format) but wasn't able to get correct result. Any other ideas?
