Dunno if anyone is still trying this. But I've got my TP-WR1043ND v1.8 running Gargoyle off a 4gb usb flash drive. If anyone's interested, I will writeup instructions... but all I did was follow these instructions.

Just used Google Translate, cause I don't know Polish. The instructions are plain simple.
