Disabling compression works fine (as temporary workaround until the issue is
solved).

Can you give this patch a try? It seems to work for Keith at least,
and it sounds like he was seeing the same problem.

Nope, unfortunately, it's not helping on my T400 laptop. I'm still

against -rc3.
What I'm using for now to fix up my system is this patch.

Ok, hopefully this is the "correct" patch. It works for me, can you
give it a try?

Subject: [PATCH] drm/i915: add FIFO watermark support for G4x
Turns out G4x needs to have sensible watermarks set, especially for
self-refresh enabled modes. Add support for it.

Here's an even more "final" patchset with some spurious hunks removed.

These patches solve the problems with severe screen flickering I
experienced on a "Mobile 4 Series Chipset" (rev07) and bisected down
to the "drm/i915: framebuffer compression for GM45+" commit
(74dff282237).
The flickering was most easily triggered by closing and opening the lid,
and was reduced or temporarily stopped by moving the mouse or pressing a
key.
