Do you mean the Hasek puzzle which starts Kb1 for white? Rh8 doesn't change the approach for white here, in fact the move order is exactly the same. You want to block the rook with the king for one move so that the white king has enough time to protect g2 before the rook arrives.

So move order (as I see it) would start:

1. Kb1 Rh8, 2. Rh6 Kxh6, 3. Kc1... etc.
