Are you sure that your CF adapter has the DMA lines hooked up? See
http://lkml.org/lkml/2006/5/23/198 for instance - IIRC, the kernel has
no way of telling whether the failure is because the card supports DMA
and the adapter doesn't, or whether the card is lying. If it's the
former, the card shouldn't be blacklisted.
