For Chumby with built-in USB wifi, it is desirable to have HUB chip on board. But, hey, this time is for hacker board, and hackers all have different, if not all wild ideas. So I assume this board needs to be generic and more like a core block with SoC and memory only, and have as much IO exposed. It is almost there, please just remove GL850G and populate OTG block, I will be thrilled.
As for kernel, I mean not only matured one like Linux, but also experimental one, such as the Inferno port I attempted months ago. The pain of swapping uSD dozen times a day was simply too much.
