Fixes a display bug seenby ajacoutot@, ok jsg@ and kettenis@.
newer X.Org (2.99.917 or master) version cause corruption on older
machines (X40, i965), probably caused by a bug in our kernel,
under investigation by kettenis@.
chipsets to the one in recent intel driver from X.Org.
- remove one of the output probe method in i830PreInit(). This method is
calling functions that are normally forbidden in PreInit(). With
xserver 1.13 this causes a fatal error at run time.
Tested by bluhm@, nick@ and shadchin@ back in september.
upsteam code.
Backporting keeping UMS changes by me, some bugfixes from kettenis@.
Has been in snapshots for a while, committed on request so we can be
sure what people are running. This is a prerequesite for sandybridge
support but has those chipsets disabled for now until the correct code
has been added.
changes from later intel versions (after the UMS removal). 95% of this
is the xvmc reworks that makes that code even halfway sane. xvmc is now
enabled by default on 965+.
Tested by many on tech@, thanks!

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.
