It seems that you have not installed the correct drivers for your card and/or 
have not defined these correctly in /etc/X11/xorg.conf, if indeed you have 
created such a file (it may not be necessary to create it unless there is a 
particular configuration need for your hardware).

I suggest you go back to the Gentoo instructions on how to install Xorg and 
retrace your steps.
