From what I've seen, modifying the grub config as you describe causes the kernel to use the EFI driver as the default framebuffer instead of VGA16. This will work for some, may fail entirely for others (i.e., those on non-EFI systems), and could result in regressions down the line due to use of this non-default framebuffer module.
