You can't break it, they said. Try, they said.

Also, port 21 is open (with vsftpd supposedly running). However all connections are refused, including telnet, nc, and filezilla. Obviously if we could get a shell, there's a lot we could do towards fixing the problem.

One last thing. This might be crazy, but is it possible to boot off of a USB stick? This would theoretically allow us to boot an arch/Ubuntu minimal USB, mount, and chroot in.

That is possible if they're using the right version of U-Boot. Unfortinately, I don't have my RoboRIO here, so I can tell you if it's the right version. But, you should also be able to boot via TFTP over the network. Hook an RS-232 up to a terminal emulator and see if there's a boot console that's visible. It's probably 115Kbps, N, 8, 1 for communications parameters. If you can get to a boot console, then you can completely reflash this beast.

HTH,
