    I have a Fujitsu S6210 laptop, which contains an O2Micro 4-in-1 Card reader.  Googling shows that many other laptops also have this reader, with noone succesfully getting it to work.

    I am using gentoo with a 2.6.8 kernel. Here is some info about the card, and how it fails

    dmesg:
    cs: IO port probe 0x0c00-0x0cff: clean.

      I don't see a datasheet for this chip on the O2Micro web site.  So I think you are out of luck until someone can get ahold of the specs.
