x86 - GPIO programming on Gigabyte motherboards

Question

I have IMB310TN motherboard with 8 GPIO pins. I'd like to use them, but there is no documentation about it. Gigabyte support responded, that documentation is confidential :). As I see, similar GPIO pins exists on various Gigabyte motherboards, so probably they should work simillary. I suspect that GPIO pins are connected to I2C bus, so I tried to identify i2c devices, but without success:

i2cdetect -l
i2c-3   i2c         i915 gmbus misc                     I2C adapter
i2c-1   i2c         i915 gmbus dpb                      I2C adapter
i2c-6   i2c         DPDDC-C                             I2C adapter
i2c-4   i2c         i915 gmbus dpd                      I2C adapter
i2c-2   i2c         i915 gmbus dpc                      I2C adapter
i2c-0   smbus       SMBus I801 adapter at efa0          SMBus adapter
i2c-7   i2c         DPDDC-D                             I2C adapter
i2c-5   i2c         DPDDC-B                             I2C adapter

The only bus where something is detected is 7:

i2cdetect -y 7
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00:          -- -- -- -- -- -- -- -- -- -- -- -- -- 
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
40: 40 -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
70: -- -- -- -- -- -- -- --                         

Unfortunately, I have no idea what to do next. Did someone succeeded to use GPIO on some Gigabyte motherboard ?
