--- Comment #17 from Anisse Astier anisse@astier.eu 2011-06-21 14:43:04 --- It's the same patch as in comment 11 which I reported tested and non-working in comment 14 . I just tested 3.0-rc4, screen is still blank and/or no backlight.
The only improvement (difference ?) seems to be in modelines detection.
