2.9.1 is the last version of the intel DDX that supports UMS (User modesetting), with 2.10 onwards being purely KMS only. As such, this driver contains backports of almost every correctness or performance related fix to the rendering layer in later intel drivers. This driver *REQUIRES* a GEM enabled kernel. it claims to support non-gem mode but this is essentially unmaintained and due to the way the abstraciton works is slow, if it works at all (it often does not). You have been warned. tested by many many people on tech over the last few weeks.
