Willie explained to me the issue around this. The SD and MMC support is
coming through the physical SD interface on the Silicon Image video chip,
instead of the SD interface on the CPU chip. (The CPU SD support is used up
already dedicated to SDIO communication with the WLAN module.)

Willie spent some time trying to write some simple test code to talk to a SD
Card but he could not get it working through the Silicon Image SD port.
Therefore the functionality is not validated at all yet, although SI have
Windows CE driver support that suggests the port silicon itself is okay.

We need to revisit this issue even with a trivial test code to confirm the
physical interface (pullups, wiring, etc) is good for production. Adding as a
blocker for BZ341/release.
