Yep, I guessed that I might have ended up with some unsupported platform.
Any ideas how I can help the developers change it into supported? :-) What

I have looked around for a module but haven't been able to find anything of
use. If anyone has a similar machine and have found an out-of-tree kernel
module, please do tell!
