Hi Peter,
I have here an Asus EEPC 1015PN the "old" bumblebee worked fine. Now I
have upgraded to Ubuntu Trusty Tahr (14.04) and tried the new one. The
bbswitch module refuses to load:

The Intel card is by default deactivated and not visible in lspci. It
was in the "old" bumblebee only activated if the script ran before the
previous shutdown.
