Good. Can you now please test the kernel stack here [1]? Install the _all headers, the amd64 headers, and the amd64 image. Then remove i915.powersave=0 and boot into the new kernel (hold down Shift while booting and select it).
This patched kernel is from Bug #538648 (specifically comment #88). It has the same graphics card and the same workaround, so it might help.
