Sure, it will have to use libhybris and Android drivers. I thought that was their major plan (to use CM hw adaptation with libhybris for Sailfish). I.e. at least until native glibc drivers for any SoC will appear. Even with efforts like Freedreno, it doesn't seem to be happening on a scale to make such SoC usable. Probably until Intel will release open drivers for their new SoC in 2015 libhybris is the only way.
