New MB, is it possible to split single PS/2 to KB+mouse? (Users)

Back to topic. I got one Gigabyte GA-P67-DS3-B3 MB and checked PS/2 connector with DMM. Unfortunately it seems like pins 2 and 6 on left side are not connected. Neither resistance nor diode test could indicate some silicon or circuit there. So there must be some switching logic to route proper PS/2 line from superIO to the same pins 1 and 5. Next I measured that there is resistance about 83ohm from superIO KCLK and KDATA to PS/2 pins 1 and 5. They are not connected with MCLK and MDATA. I cannot find where MCLK and MDATA are routed. I'll try to lift this pins up from the pads and wire them to another PS/2 port but currently I don't have any DDR3 module to run the MB.
