I have had similar problems with a TI PCI 1620 card reader and it turned out
that the ata device provided by the card reader upon insertion of a memory card
can only handle 8 bit transfers. The pata_pcmcia kernel module tries to transfer
data on 16 bits and it only transfers half of the data that's way it
says (Status 0x80)
it means the busy flag is set in the ata register since the device has
more data to transfer.
I managed to use my card reader by modifying pata_pcmcia to do an 8
bit transfer.

By the way there is another post today about transfer modes:
