I would like to use an iiyama X436S at 1280x1024 on VGA1 with my
Laptop, unfourtunatly it seems the EDID information the monitor sends
is bogus:

> VGA1 connected (normal left inverted right x axis y axis)
>   1024x768       60.0
>   800x600        60.3     56.2
>   848x480        60.0
>   640x480        59.9

The monitor is capable of 1280x1024, is it possible to override the
max-resolution, if possible without touching xorg.conf.d?
Both xrandr and kde's control center only let me select 1024x768 as
maximal resolution :/

Thank you in advance, Clemens
