No. Please see the patch I posted. It got a bit stuck as I got no reply
at all to the original query so it was filed on the low priority pile.
Simply quick fixing one case isn't the way to sort a bug like that. 

No un-nak as I've now been through and fixed the lot including a couple
of really nasty assumptions that >= UDMA_0 means UDMA mode (which isnt
true as 0xFF is no DMA)
