OSDev.org

Has/is anyone looking into doing OS hacking for one of these devices?

I'm not, but there is an interesting project from Bdale Garbee which is working looking at, called the FreedomBox. There's a presentation on it here.

As for OS-development specifics, they look cool but have enough tricky hardware (as shown by Bdale) that developing on them isn't trivial.

I'd certainly like to see more people doing OS hacking on the Bifferboard (http://www.bifferos.com), whilst the bootloader normally boots Linux it can also boot multiboot binaries, Coreboot payloads and simple binaries that are called at their load adresss. Since it's 486-compatible a lot of the stuff on osdev is relevant.

I've been fooling around with software UART code this w/e:

That is most certainly an interesting board :O

I rather like the 1W power consumption - that's the same as an ARM Cortex-A15 with on board Mali graphics!
