I'm using 3.18.9-r1 Gentoo Sources with the video_card="noveau"

Problem is my console is at 1920x1080 and I need to reduce this to 1600x900 at the highest or preferably to 1366x768 so I can read it.

Any suggestions how to do this with an EFI build?
Kernel is set to use the efi framebuffer with noveau and vesa as fall back.

Unsolvable
Turns out the problem is more complicated then I'd thought. What's happening is that my monitor only supports 1920x1080 on DVI. It's a Dell S2240M IPS display combined with the new video card **GTX 750 Ti** that doesn't have a vga port, the problem can't be solved at this time. There are indications that the nouveau driver in the 4.0 kernel gets some serious love but right now it's broke

Try adding "video=1366x768" to your kernel parameters.
Note that this may not work while efifb is in use.

use larger font. eg: compile fbcon and SUN_12x22 as static, and add kernel parameter: fbcon=font:SUN12x22

for reference:

it's a shame that your monitor doesn't support other resolutions (does it ?)
