Likely the card doesn't implement the cable detection protocol properly and so
it appears as a 40-wire cable. I think you can use the libata.force parameter
to force detection of a certain cable type (see
Documentation/kernel-parameters.txt). I'm not sure there's a good approach to
doing this automatically though, if the device IDs for the card aren't unique..
