libdrm would need b496c63143e9a4ca02011582329bce2df99d9b7c and I think
also 88e8a8bbaf026aa10225880001ab7ca1c392168a reverted.

If we're comfortable with pulling from the nouveau kernel tree[1] for
linux-backports-modules-nouveau, then going over the API bump would
indeed make cherry-picking and backporting fixes easier.  The API bump
hasn't made it out of that tree yet, as far as I'm aware.

If we're additionally going to have lbm packages for intel and radeon
built from 2.6.34, I think it makes sense to pull from the nouveau tree
now, and later switch to the .34 tree when we pull the rest of the drm
drivers for lbm.
