Nice work identifying working and non-working versions! I don't know how much time and energy you want to devote to this, but I think there are two ways we can make progress: 1) Try to convince DRM folks to help debug this. 2) Use git bisect[1] between v2.6.29 and v2.6.30. This looks like about 13 kernel rebuild/test cycles. I don't see the stable releases like 2.6.29.6 in the git repo, but you won't lose much by starting with 2.6.29.
