The drivers on intel's web site are just snapshots of the drivers that
are already in Xorg cvs.

In fact, the code is incorporated into CVS before the files are
placed on the Intel web site, so there's every reason to ignore the

Before I posted, I had looked for support for i945 chipset in the
documentation for xfree86 and   The chipset was not listed as
being supported by the i810 driver.  Perhaps the documentation was not
updated.   I did a diff on the and intel versions of the same
release and found many differences.  I did a grep on the xfree86-4.5.0
source code and did not find some code that was in the intel site.
Here is just some of what is "missing":
grep -r 'i945' xfree86intel
xfree86intel/xc/lib/GL/mesa/drivers/dri/i915/i915_texstate.c:static void
i945LayoutTextureImages( i915ContextPtr i915,
i945LayoutTextureImages( i915, tObj );
xfree86intel/xc/extras/drm/shared/drm_pciids.txt:0x8086 0x2772 "Intel i945G"
xfree86intel/xc/extras/drm/suse93/drm_pciids.txt:0x8086 0x2772 "Intel i945G"
xfree86intel/xc/extras/drm/suse93/drm_pciids.txt:0x8086 0x27A2 "Intel
Maybe I need download a specific branch of the source code and that the
latest releases do not incorporate support for the i945 chipset?
