I follow this guide compile the kernel, add video=uvesafb:1024x768-32,mtrr:3,ywrap line to grub kernel command line. The framebuffer size didn't change, one more problem the console is very slow. When I input one character from keyboard, it respond 1 second later. I checked the system status(Top, free -m) it seems no problem.
