Dear Arend,

would be nice, if you could make it clear.

I am in the exact some position (asus x205 with linux 4.0 rc3) but my
/sys/firmware/efi/efivars/ is empty. I am running debian jessie with a
kernel taken from ubuntu. Am I missing something? Even loading efivars via
modprobe doesnt change a thing.
