yes, i belive the snapcraft team together with the kernel team are
working on a fix for this [1], the snapcraft kernel plugin seems to put
the modules and firmware in a /lib subdir in the snap package which is
wrong [2] and will not make them end up in the final place on the
filesystem.

this works just fine using the official ubuntu core 16 images from [3]
as well as the daily edge images from [4] ...

(note that we do not support any non-SD card installs with the default
setup at the moment)
