Dave Vanden Bout from XESS has released an IP core for talking to an SD 
card on the XuLA2 board.
I'm not sure if it's just an I2C or SPI driver or if it has more in it 
to read and write sectors.
I find CF cards easier to use, but I suspect they are being phased out. 
They are much bulkier than SD cards.
