01:00.0 VGA compatible controller [0300]: ATI Technologies Inc M52 [Mobility
Radeon X1300] [1002:7149] (prog-if 00 [VGA controller])
    Subsystem: Lenovo Device [17aa:2005]
    Flags: bus master, fast devsel, latency 0, IRQ 16
    Memory at d8000000 (32-bit, prefetchable) [size=128M]
    I/O ports at 2000 [size=256]
    Memory at ee100000 (32-bit, non-prefetchable) [size=64K]
    [virtual] Expansion ROM at ee120000 [disabled] [size=128K]
    Capabilities: <access denied>
    Kernel modules: radeon

The following are the outputs of parsing the EDID information. The information
provided varies depending on the querying method. The information also appears
to be largely correct (although the internal panel is 14.1" and not 15"). I
don't see why xrandr is getting it's information wrong.
