Thank you for the insight and suggested solution. After having that
setting in /boot/device.hints I still cannot make the second card work,
just in case you are interested in this issue too, I have attached the
dmesg after used suggested hint. This dmesg is obtained by first insert
both cards and then boot.

And here is the output of pirtool after I used the hints and both cards:
