Do you mean a 256MB SD or 256MB MMC card in the MMC slot? A CF would have to go in a CF slot, which is rather different than SD and MMC (which I believe are serial interface, while CF is parallel memory mapped or ide (it does both)). > Do the above mentioned drivers compiled in the kernel > sufficient to use the SD/MMC interface?

I don't know that board at all, but I know a CF slot and an MMC slot would be very different to write a driver for.
