With my NEEK distribution the sd card does work reliable, but slow, as the card's SPI interface is used and not the dedicated four bit SD-Card interface. There is no free IP-Cor for the four bit interface, as you only are allowed to distribute that if you are a paying member of the SD-Card Organization (which obviously holds for SLS, who will sell you such an IP-core and uCLinux driver, if you want to and I am positive that they will support their sold products decently).

Moreover the NEEK seems to lack hardware to detect SD-Card removal and insertion and thus you manually need to reset the driver and unmount/mount the file system. I do provide scrips for this with the NEEK binary distribution.
