Looking at Xorg.0.log i can see

...
[    80.651] (II) LoadModule: "nouveau"
[    80.651] (II) Loading /usr/lib64/xorg/modules/drivers/nouveau_drv.so
[    80.651] (II) Module nouveau: vendor="X.Org Foundation"
[    80.651]     compiled for 1.19.6, module version = 1.0.15
[    80.651]     Module class: X.Org Video Driver
[    80.651]     ABI class: X.Org Video Driver, version 23.0
...

so i guess nouveau is loaded (under the control of bumblebee?).
