Gentoo on Alienware Area51m 7700

[Chiefy]

Succefull install with gentoo, everything is working.

Need some help to configure Xorg with 1920x1200 resolution

Any 7700 with 1920x1200 around? Please share your xorf.conf....

just edit it yourself. if so far you got a successful gentoo intall going, getting xorg.conf to be right should be the last of your worries. run the X -configure and then work your way from there.
