intel 950 graphics media accelerator - wrong resolution

I have a FS Amilo Pi 1505 laptop, with intel 950 graphics media accelerator chip. Worked fine (even the Beryl) with the default driver (i810) on Feisty beta 1, but the resolution is a bit strange. X only wants to run in 1024x768, though (after installing the 915resolution package) the xorg.conf shows 1280x800 (the correct values) as "Screen" dimensions. I don't know why does it jump back to 1024x768 and stretches the screen apart, but it's strange that in the Xorg.0.log file the resolutions higher than that are quite messy (strange hexa values everywhere) and somewhere around the 2073th line it says that 'Not using mode "1280x800" (no mode of this name)'. Please take a look at it, because if it affects every intel mobile chipset users it won't be good...
