[Intel-gfx] Screen flickering with kernel 2.6.33-rc3

Hello!

I recently upgraded my kernel and also have an ever-present erratic flickering 
issue...even at the console.  The screen seems to get brighter and darker.

I tracked the issue down to the following commit using 'git bisect':
    commit 18f9ed12f8c977e25d65a16af8e8d73f72417ba1
    Author: Zhao Yakui <yakui.zhao at intel.com>
    Date:   Fri Nov 20 03:24:16 2009 +0000
        drm/i915: Enable LVDS downclock feature through EDID.

This is a Lenovo ThinkPad T500 with a GM45.  I've attached the output of lspci 
-vxxx, xrandr -q --verbose, and a VBIOS dump.
