The first of hda, hdc, hde, hdg, hdi etc. that is free.

Should not need parameters.

Yes. Perhaps the CF device id isn't added to the pcmcia_pata and/or
ide-cs drivers. I don't know exactly how to retrieve the number, but
I think it's all covered in /usr/src/linux/Documentation/pcmcia/

If the kernel driver doesn't know about the id, userspace tools are
required for reading the card CIS and then for starting it up.
