It's seems https://github.com/pepe2k/u-boot_mod the bootloader could be replaced in theory. I remember the Nokia N900 Smartphone can boot from sdcard/ execute scripts from sdcard. Couldn't U-Boot on the Zsun Cardreader be modified to load a boot.scr (or whatever) from sdcard for ext root or flash a recovery from a bricked flash?
