I just tried copying the fedora rootfs to a USB stick and booting with a root= argument, but it seems to be unable to find the device at boot time even though it does get automounted, so I'm guessing some driver isn't built-in. I've also tried grabbing the sources for their default kernel and simply rebuilding, then booting the kernel over the network, but again ended up with something that couldn't read the NAND. I'll play around some more with a recompiled kernel + USB root, both their default one and the mainline-public variety. file /bin/ls on the squeeze binary shows: /bin/ls: ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.18, stripped not sure if that's enough to tell you the architecture version.
