It has an Intel i915 Chip set based embedded Graphics controller. the kernel file contains the line device agp >Description: X cant correctly support the i915 embedded graphics controller because lacking/broken kernel facilities. Symptom (from the X output): (EE) GARTInit: Unable to open /dev/agpgart (No such file or directory) (WW) I810(0): /dev/agpgart is either not available, or no memory is available for allocation. Using pre-allocated memory only. (WW) I810(0): VideoRAM reduced to 7932 kByte (limited to available sysmem) I reported this bug to the X.org folks (see [1]) and got the following answer: "Although it's PCI express, there's still a GART system. Basically FreeBSD needs to port the Linux kernel changes for AGPGART to it's kernel."
