[Bug 210780] Re: MTRRs set up incorrectly with 4GB RAM -> X slow

[D. Hugh Redelmeier]

I have a thinkpad x61t with an intel video chipset.  I have installed 4G of RAM.
I am running Intrepid with 64-bit kernel 2.6.27-11-generic.
The Intel X driver works but cannot set the frame buffer to write combining.
glxgears reports 450 FPS.

If I run mtrr-uncover (see above) and restart X, glxgears reports 650 FPS.
So the problem still exists.
