Has anyone tried this on an Intel D945GCLF board? I had already updated to the latest stable Xorg drivers when I came across this guide. I don't think that would have had any bearing on the problems I ran across but I figured I'd mention it.
I added the lines to my xorg.conf and did the workaround for the MTRR bug. I did a warm boot and made it to the greeter. After entering my login info the screen flickered a bit then I was back to the greeter. Another login attempt yielded the same result. So I logged in via a terminal and commented out the first of the new lines in xorg.conf. After that I was able to login successfully. I then started up FF and Deluge then left the machine otherwise idle for about an hour.
When I returned to the machine to do some troubleshooting, I noticed that the screen was intermittently 'fuzzy' after a few minutes of activity. Then the NB fan started spinning faster than I had ever heard it before. I disabled all the xorg.conf changes then restarted X, but the fuzziness remained. So I removed the MTRR workaround and did a warm boot. The fuzziness was still there after a restart, but eventually went away. My best guess is that the NB/VPU was starting to overheat.
You can monitor your temperatures with sensors-applet, if you wish to test your hypothesis.

I have D945GCLF, using xorg-edgers ppa and kde 4.2.3
Works actually very good if u have <10 windows.Code:Section "Device" Identifier "Configured Video Device" Option "AccelMethod" "exa" Option "EXAOptimizeMigration" "true" Option "MigrationHeuristic" "greedy" Option "Tiling" "true" EndSection
I hope performance will increase much more otherwise this motherboard is going to be used for network storage and video surveilance.
Im not saying that performance is bad though, because i personally started to track performance of xorg-edgers about 1.5 months ago and it improved about 3x no more glitches and lockups. There is some text corruption though i dont know why. This was tested on GMA 950 and X3100. (X3100 and KDE 4.2.3 wow even on 1680x1050)

Also, note that the xorg-edgers drivers aren't necessarily the fastest (hint: I gave the "Optimal" configuration its name for a reason).
People who are experiencing freezes and hard-boots can try this method so that data loss is minimal.
Start with the Ctrl + SysRq + R key combo. Wait a few seconds and press the Ctrl + SysRq + E key combo. Continue with the remaining I , S , U and B keys making sure to wait a few seconds between each key combo. These key combinations stand for:
Raw (take control of keyboard back from X)
tErminate (send SIGTERM to all processes, terminate gracefully)
kIll (send SIGKILL to all processes, terminate immediately)
Sync (flush data to disk)
Unmount (remount all filesystems read-only)
