Bug#437066: xserver-xorg-video-intel: refuses 1366x768 because detects 1024x768 panel size

["Sergey Yanovich" <ynvich@gmail.com>]

Hello Brice,

After debian/unstable bumped xorg version, I was not able to use the
old v1.7.2 driver any longer.

I have had to engineer a brute hack, but it seems to be in the spirit
of driver (there is one already).

The patch that gives me 1366x768 back is attached.

Cheers,
