Well, I did, '2014-09-17 15:38 UTC' and '2014-09-17 15:39 UTC' patches apply ok and it works.  Sorry for the inconvenience.
(perhaps one should consider pushing these two upstream instead of the fist one?)...

Title:
  [ASUS-A7K laptop] screen brightness dimmed after kernel update

Status in xserver-xorg-driver-radeonhd:
  Confirmed
Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Hello,

  Following the update from kernel version 3.13.0-34 to 3.13.0-35-generic the screen brightness got a lot dimmer.
  The Fn+F5/F6 control keys still work, in that the display gets dimmer and brighter, but the maximum brightness is too low.
  When starting ubuntu using the previous kernel release the display brightness is alright.
  I've looked around the web for ways to change the display brightness and I checked that both files "/sys/class/backlight/acpi_video0/brightness" and "/sys/class/backlight/radeon_bl0/brightness" have the maximum values, 15 and 255 respectively.

  The release I am running is : Ubuntu 14.04.1 LTS
  The XORG package version is : 1:7.7+1ubuntu8

  Please feel free to contact me for any further information.
