assembled here with my friend's equipment, i got the 9161A tab pin wrong (GND instead of power), and i managed somehow to reverse the order of the OTG pinouts 5-1, despite cut/paste from a known working board. after pulling up the 3.3v regulator and putting a top-mount OTG reversed in place of the mid-mount, powerup worked and the GL850G USB Hub came up.
tomorrow i will test the tfp401a by... you'll like this... configuring an A20 board to do HDMI output, and wiring it to the passthrough card :)

You know if this works you can't not have HDMI out on the rockchip one right?
