One thing I've noticed is that with the cbm zorro daughter board in place I get no id in the Expansion Board Diagnostic. Should I? I don't recall the board ever having its own ID.
Check the rail voltages (particularly 5V) using a multimeter, with the psu connected to the amiga - loading down the rails will be essential to get usable measurements..

The daughter board is just a "dumb" riser, and your A4K should work without it installed...
