Can you try to git-bisect the upstream git repository (on the xf86-video-intel-2.2-branch) to locate the bad commit causing this? Let me know if you need help.
ok the bug is in the 4e5c7... of 2.2-branch:
Bug 10773: fix i8xx pll p2 value in i830_crtc_clock_get()
Also fix debug dump, slightly modified to use macro instead.
and in the code:

Also, note that your dual-head config in xorg.conf is obsolete (multiple Device and Screen sections, for instance). You should read http://wiki.debian.org/XStrikeForce/HowToRandR12 to cleanup all this (or just remove your xorg.conf entirely). Let me know if you need help, again. Brice
