Hmm strange, this being bad, the commit which is reported to be broken is "drm/i915/sdvo: If at first we don't succeed in reading the response, wait", which doesn't make much sense... also I looked and before this until 2.6.38-2.29 there are no drm/acpi changes which could explain this.
Well, to confirm please try new kernel I uploaded now, 2.6.38-2.29+lp719620b3
