LaFonera Hardware SD-Card
From DD-WRT Wiki
Fonera SD Card Hack
go back to the La Fonera article.
It would be nice to be able to attach a SD Card to the La Fonera for storage.
Maybe this helps: http://forum.openwrt.org/viewtopic.php?id=8543
Also, there is a SDIO stack from Atheros http://source.mvista.com/~dsingleton/sd … SDIO-linux which besdes SD cards also intends to support "SDIO USB" which sounds even more interesting :-)
