Trying to enable i2c on Raspberry Pi 2

[Nobuto Murata]

Hi,

I'm trying to use PiGlow(LED board) with Raspberry Pi 2. Even after
loading i2c-dev module, I still cannot see /dev/i2c-1. It seems there
is an update of bcm2709 kernel on the PPA[1] which is not included in
the current image build[2] yet.

Is the new kernel(-12.12) useful to enable i2c on Pi 2?
Also is there any script to repack device-pi2-0.13.tar.xz? Because I
tried to replace the content manually with the one from PPA, but
diff[3] shows I'm missing 10 modules.* files. I'm not sure I'm in the
right direction.

Thanks,
