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 http://lkml.org/lkml/2008/4/28/115.

Yes.
I run :
xorg-server 1.4.0.90-5 ( 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.

Hmm 1.4.0.90 is not that old , is it ?
