Not my main area of expertise here, but I am not sure how this plays on 
Marvell non-kirkwood platforms (e.g., orion5x).

ISTR it is not the first time we deal with the whole IDE number of bus / 
number of ports [ / useable ports ] issue, and we may be running in 
circles here, fixing one platform and breaking another.

I'll try this on EDMiniV2 in the coming days, and let people know the 
results in this thread.
