The way to run an embedded Linux system is NOT to run off the SD card. Set up a small RAM disk and write to the disk image.
I think you could get this to work but you" have to know a little about unix-like OSes so you can make changes. That is one reason I suggested the Item Atom. It is a standard PC motherboard and can run the more common un-modified version of any OS you like. I boot them off the network or from a a USB flash drive and then un-mound the boot drive. A boot drive should be read-only and never written to.
