The box is really new so far I tested 2.6.24* 2.6.25 , linux-next , current git from
which no one worked. And yes is right graphics under Linux didn't worked right without
patch from

I run :

xorg-server ( it has all fixes from server-1.4-branch )
mesa 7.0.2-2
xf86-video-intel 2.3.0-1

Probably I have to replace 2x2G with 2x1G to get it work without this patch but it is something I don't really want to do =)

Also I'm not sure whatever this is an BIOS bug ? I could contact ASUS people if someone tells me what is wrong with the BIOS.
