Some more info about this issue thanks to Grim-a101:

    [17:45:26] <Grim-a101> Here is the kmsg when pushing power button to wake up the a101 when brightness is low
    [17:45:27] <Grim-a101> http://pastebin.com/ZBjiJZVW
    [17:46:18] <Grim-a101> the adb shell "echo 100 > /sys/class/leds/lcd-backlight/brightness" worked
    [17:47:39] <Grim-a101> need to be done before I press the power button
    [17:50:18] <Grim-a101> If I cat the file before I set it to 100, it says 0 before I press the power button, and then 30 but the screen doesn't comes up
    [17:51:04] <Grim-a101> to resume, if I don't do anything : 0 - power button - 30 but no screen
    [17:51:31] <Grim-a101> if I echo 100 : 100 - power button - 30  with screen up
    [17:52:00] <Grim-a101> back on my kernel, if you need more info, I'll be happy to reboot once again ;)
