I think that things have moved on since the first time you installed Gentoo=
=2E =20
Latest kernels have the ability to load firmware for your video card that=20
takes account of the native resolution of the monitor - without any additio=
nal=20
framebuffer drivers (like vesa, uvesa, radeonfb, etc.)  As a matter of fact=
=20
you'll get a blank screen if you try to boot the latest kernels with KMS=20
configured using any additional framebuffer driver.

To save me describing each step, you would do better reading through this p=
age=20
which details everything you need to do:
