Hi,
I'm developing a software for a device with a PCA-6782 motherboard (atom 
cpu) and an EETI touch screen display device.
The video card is an intel GMA3150.
The panel is connected by LVDS and its resolution is 800x600px (10").
My os is a debian squeeze.

Because the touch does not work properly just installing its drivers 
I've decided to follow the EETI manual and recompiling the kernel with 
some modification.

The usual guideline:
...
cat /boot/config-`uname -r` >> .config
make oldconfig

[src modification for eeti touch]

make menuconfig

fakeroot make KDEB_PKGVERSION=1.0 deb-pkg
...

The touch problem seems disappeared but now I've a new weird trouble:

The window edges are outside the real panel, It looks like that for the 
os the panel size is bigger than 10".
xrandr tell me that the is resolution is 1024x768, and if I set 800x600, 
I obtain a really poor view and still the window edges are outside the 
panel edges.

If I use an external monitor it works properly.

Any clues?
