It should only depend on the graphics chipset, not the processor, and some earlier GPUs should be supported. The wiki (http://wiki.freebsd.org/Intel_GPU) says "Initial goal is to have gen4-gen6 (and gen7 AKA IvyBridge, when available) hardware support. Gen2 and gen3 will be best efforts. See http://en.wikipedia.org/wiki/Intel_GMA for the useful table with the information about the hardware, generations and marketing nicks." Generation four is GMA X3000, five and six are... not clear to me. Maybe X3500 and X4500. > You also do not need it if you have another GPU you want to use it in the system. Yes, or put another way, the Intel driver is the only one which has working KMS at present.
