My patches are for the NetBSD kernel, not for the X server. Modern
versions of both XFree86 and X.org (i.e., from their CVS repositories)
work with i915 without kernel agp(4) support, but then you lose
X-Video, hardware cursor and possibly also some graphics performance
due to lack of graphics memory.
