    I can be found either 40 miles west of Chicago, in Chicago, or in a galaxy far, far away.

    You should not have to futz with it at all since it is probably hooked into the USB hub on the system. Just plug in a card and see what Linux thinks about it. One assumes you won't remove the USB support from the kernel...
    Sometimes, real fast is almost as good as real time.

    Thank you very much for answer Rubberman.

    Well I found the solution. Setting the following choices for the kernel:

    Device Drivers --->
    <*> MMC/SD/SDIO card support --->
    <*> MMC block device driver
    <*> Secure Digital Host Controller Interface support
    <M> SDHCI support on PCI bus

    <*> Sony MemoryStick card support (EXPERIMENTAL) --->
    <*> MemoryStick Pro block device driver
    <M> JMicron JMB38X MemoryStick interface support (EXPERIMENTAL)

    One detail. The card must be inserted during boot time.

    hopefully this post will also serve to someone else

    Regards

    If you did not insert the card before boot time, execute like root:

    #echo 1 > /sys/bus/pci/rescan //Rescan devices from PCI bus
