This is the hint: intelfb can't change the video mode. But intelfb can
be used if you /also/ add a vga to the kernel command line. I will post
mine as an example:
kernel /boot/vmlinuz root=/dev/ram0 real_root=/dev/mapper/system-slash \
ro resume=swap:/dev/mapper/system-swap vga=0x318 quiet \
video=intelfb:1024x768...@60,mttr,noaccel,hwcursor,vram=4 \
splash=silent,theme:natural_gentoo console=tty1
