Ok, finally there is some result.  After 38.3 hours Chest on a K7/600 with
350MB hash finds two key moves for a mate in 12:

PV: dxe5+ Qxe5 Bxe5+ Nxe5 Q3xg6+ N5xg6 Rxd5+ Nxd5 Qxg6+ Nf6 e5+ Ke7+ Nbd5+ Qxd5+
Nxd5+ Kf8 Qh6+ Rg7 Qxf6+ Kg8 Qxe8+ Kh7 Qh4#
PV: Bxe5+ Qxe5 dxe5+ Nxe5 Q3xg6+ N5xg6 Rxd5+ Nxd5 Qxg6+ Nf6 e5+ Ke7+ Nbd5+ Qxd5+
Nxd5+ Kf8 Qh6+ Rg7 Qxf6+ Kg8 Qxe8+ Kh7 Qh4#
