With Live Saucy, I could not success in switching from nouveau to the
nvidia driver without rebooting. By default, nouveau driver in Saucy
works with the nvidia G210M in this setup and the hotkeys for screen
brightness control work too (as well as the control itself).

I could not try the nvidia driver (nvidia-319) in Saucy, but, as I said
in comment #7, I tried the nvidia driver in Raring with
nvidia-319-updates package from Saucy repository and kernel v3.11, and
the hotkeys worked too.

Title:
  10de:0a74 [Asus UL80VT] With Nvidia discrete card, brightness
  toggleable via applet, but not Fn+F5/F6

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  With the particular setup where only the nvidia graphics card is used
  (the BIOS parameter SATA is switched from Enhanced to Compatible,
  http://wiki.daviddarts.com/Ubuntu_Maverick_on_the_Asus_UL30VT#Nvidia_Accelerated_Graphics_Driver),
  the hotkeys Fn+F5 and Fn+F6 do not produce any keypress event (tested
  with xev) but there is an ACPI event

  $ acpi_listen
  Fn+F5
  hotkey ATKD 00000024 00000018
  Fn+F6
  hotkey ATKD 00000016 0000001a

  The default setup with the Intel graphics card is related to another
