Add support for 20" display

I need two things.

I need some more information about the displays HID device. To get it open brightness controller and select: "Help -> Gather HID Information". and post the information here.

I also need to know what version of the 20" display it is. The [[http://www.everymac.com/monitors/apple/studio_cinema/specs/apple_cinema_display_20.html| 2003 with acrylic frame ]] or the [[http://www.everymac.com/monitors/apple/studio_cinema/specs/apple_cinema_display_20_2.html|2004 with aluminum frame]].

    My ACD is 2004 with aluminium frame. I use it on a PC, not Mac.

    I used windows xp before - a tool acdmon to control brightness with keyboard. In Windows 7 this tool doesn't install.

    Here's a HID information:

    Bah... apple hackers... Another display with a ton of ReportID's with no documentation hehe.

    Anyway

    <UsagePage>130</UsagePage> (VESA Virtual Controls)
    <ReportID>16</ReportID> (Brightness)
    

    is there. So no worries i can fix brightness control easy. But i don't see any support for auto brightness in your model (so far it's only the 27" models)

    I will have something ready some time this weekend.

    bootcamp drivers make no diff... as long as you don't try to use the bootcamp control panel at the same time as brightness controller.
