there can this work with new Gallium3D driver for old intel igpu ?

Definitely not, IGC intentionally only supports Skylake and above. It's also a purely scalar-mode backend, and the GPUs supported by crocus require operating the hardware in vector-mode for the vertex, tessellation, and geometry stages. They would have to write a whole new backend from scratch just to support old hardware, and that's very unlikely to happen.

The Mesa Intel compiler backend (brw_vec4/fs) does continue to support those platforms.
