Reverting that patch (or, more accurately, just deleting the redundant = backlight_off call) does indeed solve the problem when initially = starting X. So now it's just the suspend issue. Same behavior as 2.6.34: = when resuming, the display is off, and switching VTs, etc., won't turn = it on. What does work, if I type very carefully, is hibernating and then = resuming.
