I have a USB card reader that only worked if I issued "hdparm -z /dev/sdX", for some reason the device only worked after the second time it was initialized. I don't know if you're using USB or MMC interface for your card reader but maybe you can try it. I have another device that used the MMC driver, it didn't work properly with fast cards (above class 4) -- massive corruption every time -- the "fix" was to hardcode the DTO value of 0xA in the mmc driver (instead of dynamic calculation), after that it worked fine...
