Driver for Ricoh sd card - XPS 1530

Hi:

I have a  XPS1530 C2D 7250/4GB ram/HD 200GB 7200rpm/8600Gt 256ram 1680x1050/Ricoh SD card R5C592 rev 22

I have Vista Home, no problem here, but, the os I use is Mandriva 2008.1

all hardware works fine except the reader memories Ricoh. The device is detected by the system. It appears on the list of hardware without errors. The syslog not reported any error. Only get a message saying that "the driver has been disabled"

I did not find in the forums of Dell any item related to the reader.

I have tried kubuntu and ubuntu in live mode. Same problem. when I put a card, it is not detected.

Anyone know where I can find drivers for Linux?

Thank you
