any progress on this? I have one of these access points available right now 
for hacking (as long as I do not brick it). The last hours I made those 

The libc of UBNT 3.2.7 seems to be compatible to tools of the old kamikaze 
release (http://downloads.openwrt.org/kamikaze/8.09/ar71xx/packages/). So far 
I've tested io for looking at the gpio ports and strace.

It seems that the filter it not statically connected to gpio. By adressing 
AR71XX_GPIO_REG_SET and AR71XX_GPIO_REG_CLEAR, I could switch the blue and 
white leds as expected:

/tmp/io -4  -w 0x18040010 1  # blue off
/tmp/io -4  -w 0x1804000c 2  # white on

Ten GPIO lines seem to be configured as output:

/tmp/io -4 -r 0x18040000
18040000:  00000cff

However, independant of the channel selected the ports are always set to 
0x00081405 (or 0x00081404 or 0x00081406 depending on the LED setting):

BZ.v3.2.7# /tmp/io -4 -r 0x18040004
18040004:  00081405

If anyone has ideas where else to look, please share. Meanwhile let's see what 
I can do with strace ;-)
