Details:

I was trying to activate the framebuffer after my grub2 installation.

With the following menuentry it worked, but with just 1024x768 as
resolution:

menuentry "Gentoo GNU/Linux, Linux 2.6.30-gentoo-r4" {
        insmod ext2
        set root=(hd0,1)
        search --no-floppy --fs-uuid --set 868e7b2d-ad98-4f62-927e-aaceae9073ce
   gfxpayload=1024x768x32
        linux   /kernel-2.6.30-gentoo-r4 root=/dev/sda3 ro  
}

If I change the resolution to 1680x1050x32, there is a real resolution of
640x480 and a brightness of about 50%.
If I use linux16 and vga=0x369 it worked like it did before (grub1).
I am having a nvidia graphic card:
