I installed osmc on a Raspberry Pi 2 and everything worked smoothly out of the box, one of the best IT experiences I had in a long time. Congratulations on that!
When trying to upgrade my WLAN stick connected to it to a 802.11ac one I was confronted with the need to compile the driver provided by the manufacturer myself, but the package repository does provide kernel sources only for 4.3.3-2 (rbp2-source-4.3.3-2-osmc), whereas my device runs on 4.3.3.-3. Is it intended that there is no source package for my kernel version?
