Sorry, but that won`t work, since the DKB3128 uses DMA and only 5 (or was it 6) of the slots are able to do DMA (like the commodoreguidelines stated), the others are non DMA. There were some Eagleboards that even had 8 Zorro III Slots.
I`m not sure how this ist handled, if there are up to 5 DMA-cards possible at once in any slot, or if simply Slot 1-5 can do DMA and the others don`t
