Optimus started out that way, but they might use the same name now for models where the additional GPU is a full discrete adapter. > Anyway, I also tried to configure X11 as HD4600 only and X11 doesn't work properly: it > doesn't even start up and loading the "intel" driver complains about a missing device - > preceeded by a lot of /dev/dri errors.

Whoops, HD4600 is Haswell. The intel driver on FreeBSD does not support Haswell video yet.
