#1 Does not work with ACD led 24'', fix added

[rwd2]

I tried to get ACD Display backlight control to work with this setup:

- Apple Macbook Pro 7,1 (2010)
- Apple Cinema Display 24'' LED ( the one with mini displayport)
- Running Arch Linux

By default the monitor is not supported:
[code[
sudo ./acdcontrol --detect /dev/usb/hiddev*
Apple Cinema and Studio Display Control Program. Please, use --about switch to learn more
hiddev driver version is 1.0.4
hiddev driver version is 1.0.4
/dev/usb/hiddev1: USB Monitor - UNSUPPORTED. Vendor= 0x5ac (Apple), Product=0x9236
[/code]

After recompiling using this in acdcontrol.cpp it worked:

"const int CINEMA_DISPLAY_24 = 0x9236;"

[code]
sudo ./acdcontrol --detect /dev/usb/hiddev*
