Turn out the gpio pins simply go from 0 at the right edge (LAN1 LED) up to 7 (power). Only the least significant bit of the value has meaning.

7 1=disable (sic)
6 1=enable
5 0=disable
0-4 0=green

I suppose the kernel handles blinking the WLAN LED, but it can be disabled. The WAN and LAN indicators can change color, but are probably hardwired (anybody has a hires shot of the board?) so I'm out of luck as far as annoying flashing is concerned.
