If you find out, how your card is mapped to memory, you can dump that memory range which will take about 20 hours, or probably twice that much, because PC cards are only 16 bits wide, but Hammer dumps 32 bits.

They are not memory mapped as in the MessagePad, but instead are mounted like a harddrive and behave very similar. You can read thos cards with any 20$ PCMCIA to USB reader, but you can't use those files on a MessagePad. Newtons have their own disk format that is more like a database than a desktop file system. Only very few file types can be converted.
