Just for a reference of someone who did at least close to this:
http://webpages.uncc.edu/~jmconrad/ECGR6185-2008-01/notes/SD_CARD_DISPLAY_MICROCONTROLLER.pdf these guys did it.
Code here ftp://ftp.circuitcellar.com/pub/Circuit_Cellar/2007/209/Davaine-209.zip .

http://electronics.stackexchange.com/questions/29010/sd-card-emulation even suggests that SPI wouldn't be enough but that modern SD cards go "25Mhz".. what's the issue?
How would you implement this?
Also any more references on this forum would be much appreciated.
