raw = usable for input AND output, switches probably are too but not tested
there's probably something I missed, if anyone knows others please say so :)
"top" viewed with switch ports on the left

gpio0 - ledb4 unpopulated raw
gpio1 - power sw blinker active low
        present on UB14 top (without blinking)
gpio2 - DONT TOUCH - assumed sw reset - will cause kernel panic if driver is running
        (in)active low
        present inverted on rb222 top (near switch)
gpio3 - amber ledb2 active low raw 
gpio4 - DONT TOUCH switch control? - causes errors
gpio6 - reset sw active low input
gpio8 - top security switch active low input
gpio9 - green ledb2 active low raw
gpio10 - green ledb10 blinker active low
        raw on UB16 top (without blinking)
gpio11 - green ledb10 active low (yes, this overrides gpio10)
        raw on ub17 middle
gpio13 - unpopulated ub19 middle raw

gpio5 - present cb171 bottom of board at 5v
        raw ub13 top right
        can cause the same errors as 4
