 Maybe this is similar to the problem I have with the Picasso in Z2-
machines equipped with 040. Some of the registers are not correctly
addressed by the 040 due to the Zorro-to-ISA (or VESA) convertion.

 The little/big endian problem strikes for the palette registers in
the Picasso - maybe this is the case for other registers in the Retina?
