For radeon it seems clear that we need the 2.6.33 code or stay with UMS,
and nouveau is not in .32, so basically the question seems to be about
i915.  My impression is that 2.6.32 was quite bad, and 2.6.32.x has
gotten it into a better shape (except for 8xx, but that's been broken
for quite a while, and not just with kms, so...).  Now if we're
confident that either i915 in 2.6.33 is better than .32.9 already or
that the regressions it introduces can be fixed in the next month or
couple of months, then backporting drm from .33 seems like it would be a
good thing to do for squeeze.
