You can talk to SD using MMC fallback mode. However, this mode doesn't 
let you use the (BS!) DRM features built into the spec. That's the 
secret part. Depending on the appliance that wrote the card, you may or 
may not be able to access already-written data.

I haven't seen a Linux driver for raw SD. I've seen drivers for 
mass-storage devices that use it, of course... But if these drivers do 
exist, arm-linux would be the place to find them. I don't see how it 
could be released opensource though - the SD spec has stringent 
nondisclosure requirements.
