Reporters, please take into account that the solution for this issue is composed by a kernel patch and a xorg patch.
The first one provided by Andy at http://people.ubuntu.com/~apw/lp314928-jaunty/
The second one provided by Bryce's magenta PPA https://edge.launchpad.net/~bryceharrington/+archive/magenta
The kernel patch sets correctly the MTRR and the Xorg one assures that reloading xorg doesn't wipe it.
Please reporters with the same issue, test both, and confirm here to move those to normal updates (i believe they aren't there yet.)
