I've just looked at the changelog for the 2.6.27 kernel, and there's no mention of brightness in patch 10 and 11. Maybe something completely different is interfering. There seems to be some patch with brightness in the patch 15 and 16. For an unknown reason I can't compile kernels, but if you can try to see if it gets solved.
