Joques: I saw your other post first and responded. I'll make the some comment here for others to see:
I would say that nickel is checking if the kernel supports the light and two finger touch. The 3.7.0 package only has kernels for the Aura and Aura H20, so if you installed this on the Glo, it is still using the same kernel as before.
It's a good option, but it will be interesting to see what is in the next firmware for the different devices
