You will have to revert
http://cgit.freedesktop.org/xorg/driver/xf86-video-intel/commit/?id=8d4bc36fae50b09a73ba2cfab920adb32141a358
or for 2.6 branch:
http://cgit.freedesktop.org/xorg/driver/xf86-video-intel/commit/?h=2.6&id=133dd16356c0a6d63a62b8cf3cbb2c2ba41ee2d9

I had to do this for the trunk build a while ago, but not any longer.
I /think/ what makes the difference is that the i915_drm.h is picked
up from libdrm_dev and not from the 2.6.28 kernel headers.

In configure.ac, set a conditional to no,no instead of yes,no. See the
Ubuntu package, or the xorg-edgers auto-xorg-git hook for -intel.

But, if you only want to verify a VGA detection issue, just download
the main Ubuntu source package (no xorg-edgers) with "apt-get source
xserver-xorg-video-intel" and add your patch before you build it with
"debuild -b -us -uc".
